CDC 2r071 Vol. 1 Maintenance Management

The probability of making a type I statistical error is denoted by alpha (α). Type I error occurs when the null hypothesis is rejected, even though it is true. Alpha represents the significance level, which is the predetermined threshold for rejecting the null hypothesis. It determines the likelihood of falsely rejecting the null hypothesis when it is actually true. Therefore, alpha is the correct answer to the question.

The correct answer is "by using commands to initiate Temporary–1 and Temporary–2 modifications." This is because an Air Force Form 1067, Modification Proposal, is used to initiate temporary modifications, specifically Temporary–1 and Temporary–2 modifications. This form allows for the submission of proposed changes and includes the necessary information to implement these temporary modifications through the use of commands.

The purpose of the weekly utilization and maintenance plan is to refine the monthly maintenance plan and provide additional details to it. This means that the plan is not meant to present operational requirements or maintenance requirements for the current week, nor is it meant to provide a complete detailed listing of deviations from the previous week. Instead, it is specifically focused on improving and adding more information to the monthly maintenance plan.

If the engine data plate is not accessible during the physical inventory, the appropriate action to take is to review the aerospace vehicle engine documents. This is because the engine data plate contains important information about the engine, such as its serial number, model number, and other specifications. By reviewing the aerospace vehicle engine documents, one can find the necessary information about the engine and ensure accurate inventory records are maintained.

Temporary modifications are made to equipment in order to enhance its capabilities for a specific purpose or mission. In this case, the modifications are specifically intended for special missions, indicating that they are not meant for combat, alert duty, or general deployment. These modifications could include adding or removing equipment to better suit the unique requirements of the special mission at hand.

The correct answer is 1200 hours Friday preceding the effective week. This means that the weekly plan should be developed and distributed to all maintenance work centers no later than 1200 hours on the Friday before the effective week.

There are three basic time compliance technical order categories that are authorized.

The chi-square test can be used for any number of samples in nonparametric testing. This test is used to determine if there is a significant association between categorical variables. It compares the observed frequencies of different categories with the expected frequencies to assess if there is a significant difference. The number of samples does not limit the applicability of the chi-square test, making it a versatile tool in nonparametric testing.

The maintenance operations center's internal control is exercised when all resources are in a single squadron. This means that all the resources, such as personnel, equipment, and supplies, are consolidated within one squadron. This allows for better coordination, communication, and oversight of the maintenance operations. Having all resources in a single squadron streamlines the decision-making process and ensures that the maintenance operations are effectively managed and controlled.

The Major command is responsible for devising procedures to ensure the maintenance activity receives its quarterly allocation of flying hours. They oversee and coordinate the activities of multiple wings and units within the command, ensuring that resources are allocated appropriately and that all units receive their required flying hours. This role is crucial in maintaining the readiness and operational capability of the command's aircraft.

The correct answer is 2005. The question is asking for the Air Force Form number that the aircraft maintenance unit uses to order noncartridge-actuated device/propellant-actuated device or engine time change items. The answer is 2005 because it is the only option provided that matches the criteria given in the question.

Maintenance operations is the correct answer because maintenance supply liaison personnel are physically located in the maintenance operations department. This department is responsible for coordinating and overseeing all maintenance activities, including the supply and logistics aspects. Therefore, it is logical to assume that the maintenance supply liaison personnel would be located in this department to ensure effective communication and coordination between maintenance and supply functions.

The Standard Base Supply System is programmed to reject due-in from maintenance (DIFM) issues for more than one item because there is a possibility of having different maintenance actions taken on items with only one document number. This means that if multiple items are included in one document number, it may be difficult to track and manage the different maintenance actions required for each item. By rejecting multiple DIFM items, the system ensures that each item receives the appropriate maintenance action and is properly tracked.

The objective of the Air Force Repair Enhancement Program is to reduce the total Air Force material costs. This means that the program aims to find ways to decrease the expenses associated with repairing and maintaining equipment and materials used by the Air Force. By implementing cost-saving measures and strategies, the program can help the Air Force allocate its resources more efficiently and effectively, ultimately leading to a reduction in overall material costs.

The correct answer is the installation deployment officer. The deployment control center is activated and controlled by the installation deployment officer, who is responsible for overseeing and managing the deployment of personnel and equipment. They coordinate with the logistics group commander, unit deployment manager, and installation commander to ensure a smooth and efficient deployment process.

Food service requirements should be included as a portion of the detailed support requirements in the maintenance plan. This is because the maintenance plan should outline all the necessary support and resources needed to maintain and service the aircraft. Food service requirements are an important aspect of this as they ensure that the necessary provisions and facilities are available to cater to the needs of the crew and passengers during maintenance operations.

The purpose of daily planning is to verify the daily portion of the weekly maintenance plan with operations. This suggests that operations plays a role in ensuring that the daily maintenance plan aligns with the overall goals and objectives of the organization. Operations may provide input and feedback on the feasibility and practicality of the plan, ensuring that it is aligned with the operational needs and priorities of the organization. This collaboration between daily planning and operations helps to optimize maintenance activities and ensure efficient use of resources.

The index type of technical order (TO) provides a means of selecting needed TOs, showing the status of all TOs, and grouping the TOs pertaining to specific items of equipment. An index TO serves as a reference guide that allows users to quickly locate the specific TOs they need for a particular equipment or task. It helps in organizing and managing the TOs effectively by providing a comprehensive list and categorization of all available TOs.

The minimum dollar value required for some item discrepancies before submitting a supply deficiency report is $100. This means that if the value of the discrepancies is less than $100, a supply deficiency report does not need to be submitted.

Inventory reporting is divided into two distinct types: assignment and possession. Assignment refers to the process of assigning inventory to a specific individual or department, ensuring accountability and tracking. Possession, on the other hand, refers to the physical possession of inventory by a specific individual or department. These two types of reporting help in accurately tracking and managing inventory, ensuring that it is properly assigned and accounted for.

The group of a technical order (TO) number that primarily identifies the type of TO, instruction, or procedure is the third group. This group provides information about the category or type of TO, such as maintenance, operations, or training. The other groups in the TO number provide additional information, such as the specific system or equipment being addressed.

The symbol used on weapons systems forms to indicate a condition that will prevent the successful launch of a missile is a red W. This symbol is commonly used to denote a warning or cautionary condition that could potentially hinder the launch process. The red W serves as a visual indicator for personnel operating the weapons system, reminding them to address the issue before attempting to launch the missile.

When the Maintenance Information System (MIS) is available, it replaces the Air Force Technical Order Form 95 to document significant historical events on aircraft, engines, and equipment.

Under the Intermediate Repair Enhancement Program review, a repair cycle bottleneck is considered to be frozen supply records. This means that there is a delay or inability to access necessary supplies or materials needed for the repair process. This can significantly slow down the repair cycle and hinder the efficiency of the program.

The correct answer is "Cardholder only." This means that only the individual who holds the government purchase card is authorized to use it under one account. The approving official (AO) and commander do not have the authority to use the card, as it is solely the responsibility of the cardholder.

The concept of reporting based on exception reporting in Air Force Instruction 21-103 is related to the status of reporting. Exception reporting means that only significant or exceptional events or changes are reported, rather than reporting every single detail. This approach allows for a more efficient and streamlined reporting process, focusing on important updates or deviations from the norm. Therefore, the correct answer is "Status" as it aligns with the concept of exception reporting in the context of the Air Force Instruction.

The stock record account number engine manager is responsible for ensuring that the Integrated Maintenance Data System (IMDS) and the Comprehensive Engine Management System (CEMS) contain the same information. This is important to maintain accurate and consistent inventory records and to ensure that all relevant information about the stock is available in both systems.

A time compliance technical order is classified as depot-level maintenance when it requires more than the normal time factors of 8 clock-hours or 25 man-hours.

When you assign a level of significance to a statistical test, you are actually assigning a certain proportion of data in the normal curve area as your rejection region. This means that if the test statistic falls within this rejection region, you reject the null hypothesis. The level of significance determines the size of this rejection region, with smaller levels of significance leading to smaller rejection regions and therefore a higher standard for rejecting the null hypothesis.

Six Sigma represents 99.9997% of all data points in a normal distribution. This means that only 0.0003% of data points fall outside of the acceptable limits, making it an extremely high level of quality control. Six Sigma is a methodology used in business to improve processes and reduce defects, aiming for near-perfection in performance.

Self-inspections should be conducted quarterly. This frequency allows for regular monitoring and assessment of the organization's operations and compliance with policies and regulations. Conducting self-inspections on a quarterly basis ensures that any issues or non-compliance can be identified and addressed in a timely manner, preventing potential risks and maintaining the overall effectiveness of the organization's processes.

The correct answer is JFP. JFP is the Integrated Maintenance Data System transaction identification code used to load, change, delete, and inquire all pertinent data required for establishing a job standard.

The correct answer is unit identifier code, unit descriptor code, unit level and type, and organizing MAJCOM. This is because when reporting Status of Resources and Training System data, the basic identity includes information about the unit, such as its identifier code and descriptor code, as well as its level and type. Additionally, the organizing MAJCOM is also included to provide further context and classification of the unit.

The purpose of an F test in parametric testing is to determine if significant differences exist between two variances. This test compares the variances of two groups or populations to determine if they are significantly different from each other. It is used to assess the homogeneity of variances and is commonly used in analysis of variance (ANOVA) tests. By comparing the variances, the F test helps to determine if there are significant differences between the groups being studied.

The Kruskal-Wallis H test is a non-parametric test used to compare three or more independent groups. It is based on the rank of the data rather than the actual values. Ordinal data is data that can be ranked or ordered, but the differences between the values may not be equal. Since the Kruskal-Wallis test is based on ranking, it requires data from at least an ordinal scale.

When plotting a line of regression, you establish a range within which a given proportion of the values will fall. This is because regression analysis involves predicting values based on a line of best fit, and there is always some degree of error or variation in these predictions. By establishing a range, you can account for this variation and have a measure of confidence in the predicted values. This range is typically determined by calculating the standard error of the estimate, which quantifies the average amount of error in the predictions.

Modification management is a process that involves making changes or modifications to systems. The purpose of these modifications is to correct any deficiencies or issues in the system and to improve its reliability, maintainability, and capability. This process does not specifically focus on increasing contract efficiency or reducing cost, although these may be potential benefits of the modifications. The correct answer states that modification management aims to correct deficiencies and improve reliability, maintainability, or capability, which aligns with the purpose of this process.

A cartridge-actuated device/propellant-actuated device time change item must meet a service life time parameter of 9 months for munitions operations to not reissue the part.

The correct answer is Time Sharing Option. The Time Sharing Option is used in the Comprehensive Engine Management System (CEMS) application for requesting products from the database and browsing, submitting, and viewing products. It allows users to access and interact with the CEMS database in a shared time environment, enabling multiple users to use the system simultaneously. This option facilitates efficient product management and enhances the overall functionality of the CEMS application.

An immediate action time compliance technical order is issued when there are conditions that, if not corrected, could lead to fatal or serious injury to personnel or extensive damage to valuable property. This means that the issue at hand requires immediate attention and corrective action to prevent any potential harm or damage.

The red dash symbol on an aircraft form indicates that the condition of the equipment is unknown and there may be a more serious condition present. This symbol is used to alert maintenance personnel that further investigation is required to determine the exact condition of the equipment. It signifies that there is uncertainty about the equipment's operational status and that it may pose a potential risk or problem.

Tuition has specific rules that must be complied with before paying with the government purchase card. This could include requirements such as providing documentation of enrollment or proof of eligibility for the tuition payment. The government likely has specific guidelines and regulations in place to ensure that funds are used appropriately for educational purposes.

To determine whether an outlier exists in a distribution, the first thing you must do is plot the data on graph paper. This allows you to visually observe any extreme values that may be present in the data. By plotting the data, you can identify any points that are significantly different from the rest of the distribution, which may indicate the presence of an outlier. Once you have plotted the data, you can then proceed to further analyze and interpret the distribution.

The correct answer is "failure would cause an increase in supply requisitioning time." This is because items that are not in any category for time change replacements are those whose failure would result in a delay in obtaining necessary supplies. This delay in supply requisitioning time can have negative consequences and impact the overall efficiency and effectiveness of operations.

The correct answer is JFI. The JFI transaction identification code in the Integrated Maintenance Data System allows users to inquire the database for information on job standards and also provides the ability to inquire a job flow package. This code can be used in any of the three available formats to access the desired information.

The correct answer is "get due-in from maintenance parts turned around as fast as possible." This means that the overall objective of the Repair Cycle Support System is to ensure that maintenance parts that are due for repair are processed and returned as quickly as possible. This objective focuses on minimizing downtime and maximizing the availability of repaired parts for use in maintenance activities.

A supply deficiency report is considered unresolved if a reply has not been received within a certain timeframe. In this case, the correct answer is 146 days. This means that if a reply to the supply deficiency report has not been received within 146 days, it is still considered unresolved.

Air Force Form 2409 is the correct answer because it is specifically designed to document and track required maintenance actions for sortie generation against a specific line number. This form is used to record the maintenance actions performed on an aircraft, including inspections, repairs, and servicing. It ensures that all necessary maintenance tasks are completed before the aircraft is cleared for a sortie, helping to maintain the safety and readiness of the aircraft. Forms 2406, 2407, and 2408 may be used for other maintenance purposes, but they do not specifically address the required actions for sortie generation against a specific line number.

The correct answer is 30. This means that the maintenance operations flight plans, scheduling, and documentation monitors time compliance technical order (TCTO) status and briefs unaccomplished TCTOs within 30 days of grounding at the maintenance group level each week.

The base-level segment of the Comprehensive Engine Management System serves as the initial collection point for engine status and component operational data. This means that it collects information about the current state of the engine and the operational status of its various components. This data is important for monitoring the engine's performance, identifying any potential issues or malfunctions, and making informed decisions regarding maintenance and repairs.

A special experience identifier is used to indicate the qualification of an individual. It helps to identify the specific skills, knowledge, or experience that a person possesses in a particular field or job role. This identifier is used as a way to assess and evaluate the qualifications of individuals for specific positions or tasks. It helps in determining whether an individual has the necessary qualifications and expertise required for a particular role or job.

C-4 rating means that the unit requires additional resources or training to undertake its wartime mission(s), but it may still be directed to undertake portions of its wartime mission(s) with the resources it currently has. This suggests that while the unit may not be fully equipped or trained for its mission, it is still capable of performing some tasks with the available resources.

In a z test, the sample size for differences between sample means should be at least 30. This is because a larger sample size provides more accurate and reliable results, reducing the margin of error and increasing the power of the test. With a sample size of 30 or more, the Central Limit Theorem can be applied, allowing for the assumption of a normal distribution of the sample means. This is important for accurate hypothesis testing and confidence interval estimation. Therefore, a sample size of at least 30 is recommended for z tests.

In probability statistics, numbers of personnel, failures, cars, airplanes, and radar sets are considered discrete data. Discrete data refers to values that can only take on specific, separate values and cannot be measured on a continuous scale. In this case, the numbers of personnel, failures, cars, airplanes, and radar sets can only be whole numbers and cannot be measured as fractions or decimals. Therefore, they fall under the category of discrete data.

A line of regression in regression analysis indicates the trend of the data relationships. It shows the direction and strength of the relationship between the dependent variable and the independent variable(s). It helps in understanding how the dependent variable changes with respect to the independent variable(s) and can be used to make predictions or draw conclusions about the data.

The correct answer is TDI. TDI stands for Time Display Information. In Integrated Maintenance Data System, the TDI transaction identification code is used to generate a graphic display that shows the time remaining to inspection, profile, or time change for each item of equipment under the input equipment designator. This display helps in keeping track of the maintenance schedule and ensures timely inspections and changes are carried out.

In manpower studies using the logistics composite model, the objective is to determine the lowest manpower level possible to achieve the desired sortie rate for each Air Force specialty. This means that the focus is on finding the minimum number of personnel required for each specific job within the Air Force, in order to maintain the desired level of operational readiness and efficiency. The study aims to optimize manpower allocation and ensure that each specialty has the necessary personnel to fulfill their role effectively.

When the basic assumption for a z test for means cannot be met, the appropriate test to use is the Mann-Whitney U test. This test is a non-parametric test used to compare two independent groups when the assumption of normal distribution or equal variances cannot be met. It is used to determine if there is a significant difference between the medians of the two groups. The Mann-Whitney U test is a suitable alternative to the z test for means when the assumptions for the z test cannot be fulfilled.

An aircraft document review is necessary to ensure that all necessary forms and records are properly filled out and up to date. This is especially important for units using fully automated Air Force Technical Order 781-series forms. Conducting this review every 60 days allows for regular checks and updates to be made, ensuring that all necessary documentation is accurate and complete. This timeframe strikes a balance between conducting the review frequently enough to catch any errors or discrepancies, while also allowing for operational efficiency and minimizing disruptions.

The correct answer is "decide and act." The eight-step problem-solving model involves a continuous loop of observing, orienting, defining, deciding, acting, and then repeating the process. The "decide and act" step refers to making a decision based on the information gathered and taking action to solve the problem. This step is crucial in implementing the chosen solution and moving forward in the problem-solving process.

A parametric type of statistical test assumes that the data follows a specific distribution, usually the normal distribution. Therefore, the characteristic that best applies to a parametric type of statistical test is that the random samples should be from a normal distribution.

The probability that two events will occur together or in succession is determined by the multiplication rule of probability. This rule states that the probability of both events happening is the product of their individual probabilities. In other words, to find the probability of both events occurring, we multiply the probability of the first event by the probability of the second event. Therefore, the correct answer is multiplication.

The data base reconciliation listing for time compliance technical order status on engines is accomplished on a quarterly basis. This means that the reconciliation is done every three months to ensure that the engines are in compliance with the required technical orders. This regular and frequent reconciliation helps to maintain the engines' performance and safety standards.

Major command commanders assign functional area offices with the responsibility for each measured unit type in the Status of Resources and Training System. This means that the commanders at the major command level are responsible for determining which functional area offices are responsible for each measured unit type in the system.

The mean of the squared deviations from the arithmetic mean represents the variance. Variance measures the spread or dispersion of a set of data points around the mean. It calculates the average of the squared differences between each data point and the mean. A higher variance indicates a larger spread of data points from the mean, while a lower variance indicates a smaller spread.

The correct answer is PRA. PRA stands for Planned Replacement Assembly, which is a background Integrated Maintenance Data System transaction identification code that provides the capability to list maintenance requirements and forecasts of time changes and inspections for equipment specified in the input. This code helps in planning and scheduling maintenance activities for specific equipment.

In a chi-square test, the degrees of freedom are calculated by subtracting the number of categories minus 1 from the number of rows minus 1. In this case, there are 5 categories and 4 rows, so the degrees of freedom would be (5-1) * (4-1) = 4 * 3 = 12.

A t test is used to evaluate the significance of the difference between the means of two small samples. This statistical test helps determine if the observed difference between the means is statistically significant or if it could have occurred by chance. The t test takes into account the sample size, the variability within each group, and the difference between the means to calculate a t value. By comparing this t value to a critical value from the t distribution, the test determines if the observed difference is statistically significant or not. Therefore, the correct answer is means of two small samples.

When you need to know the probability of two independent events occurring at the same time, you determine the answer by adding the two probabilities. This is because when two events are independent, the probability of both events happening is equal to the sum of their individual probabilities.

The function of the technical order (TO) distribution account is to conduct and document routine TO catalog checks and annual TO library inventories. This ensures that the TOs are properly organized, accounted for, and available when needed. It helps in maintaining accurate records and identifying any discrepancies or missing TOs. This function is important for the efficient functioning of the technical order distribution office and ensuring that the organization has access to the necessary technical manuals and instructions.

The correct answer is ITF. The ITF transaction identification code inquiry lists all inspections, time changes, and time compliance technical order requirements against a specific aircraft or part/serial number.

When measuring a unit's mission ready rates, the factor that belongs to the Status of Resources and Training System (SORTS) resource area is equipment condition. This means that the readiness of the unit's equipment, including its functionality, maintenance status, and overall condition, is taken into account when assessing its mission readiness. The other options, such as training, personnel, and equipment and supplies on hand, may also be important factors in determining readiness, but in this specific question, the correct answer is equipment condition.

In data correlation for regression analysis, the measure of dispersion refers to how spread out the data points are from the regression line. The standard error of the estimate is a statistical measure that quantifies the accuracy of the regression model's predictions. It represents the average amount by which the actual values deviate from the predicted values. Therefore, the correct answer is "error of the estimate."
