CDC 2r051 Vol. 4 Maintenance Performance Measurement

High repeat and recur rates may indicate a lack of thorough troubleshooting. This means that when issues or problems occur repeatedly or frequently, it suggests that the troubleshooting process has not been thorough enough to identify and address the root cause of the problem. If thorough troubleshooting had been conducted, the underlying issues would have been identified and resolved, resulting in lower repeat and recur rates. Therefore, the correct answer is thorough troubleshooting.

The first step in the analysis process is to collect the data. This is because without data, there is nothing to analyze. Collecting the data involves gathering relevant information from various sources, such as surveys, interviews, experiments, or existing databases. Once the data is collected, it can then be manipulated, compared, and verified in order to draw meaningful conclusions and insights.

The correct answer is Mean time between failure (MTBF). MTBF is a measure used to determine the average time that a piece of equipment operates before experiencing a failure. It is calculated by dividing the total operating time by the number of failures that occur. This measurement is important in assessing the reliability and performance of equipment, as a higher MTBF indicates a longer average operating time before failure.

When an aircraft is cancelled due to bad weather, it falls under the nonchargeable deviation category. This means that the cancellation is not counted against the pilot or the airline and does not result in any penalties or charges. Bad weather is typically considered an uncontrollable factor that is beyond the control of the pilot or the airline, and therefore, they are not held responsible for the cancellation.

The Accomplishment Utilization Report (AUR) is the correct answer because it provides information about the total number of cancellations. The AUR is a report that tracks the utilization of resources and accomplishments within a specific timeframe. It includes data on various operational events, including cancellations. Therefore, by referring to the AUR, one can obtain the total number of cancellations. The other options, such as the Daily Flying Schedule, Operational Event Report, and Monthly Maintenance Plan, may provide relevant information but do not specifically focus on cancellations.

The correct answer is "keep current with IMDS issues." This is because the purpose of the Integrated Maintenance Data System (IMDS) Users' Group meeting is to stay updated and informed about any issues or updates related to IMDS. The group meets regularly to discuss and address any problems or concerns, ensuring that members are knowledgeable and up to date on IMDS matters.

The correct answer is 4, 8, or 12 hours. This means that the fix rate formula can be calculated using any of these three time frames.

The correct answer is to undertake a logical and systematic approach to solving it. Once you have identified that there is a problem with high NMCM and overtime rates, the next step is to approach the issue in a logical and systematic manner. This involves analyzing the root causes of the problem, gathering relevant data, and developing a step-by-step plan to address and solve the issue effectively. By taking a logical and systematic approach, you are more likely to identify the underlying causes of the problem and implement appropriate corrective actions.

When using text on a presentation slide, it is recommended to use bullet statements instead of paragraphs. This guideline helps to make the information more concise and easier to read and understand for the audience. Bullet points allow for key points to be highlighted and presented in a clear and organized manner, while paragraphs can be overwhelming and difficult to follow on a slide.

Depot maintenance is considered the highest level of maintenance for more complex repairs. Depot maintenance involves extensive repairs and overhauls that cannot be performed at lower levels of maintenance. It typically includes major repairs, component replacements, and refurbishments of equipment. This level of maintenance is usually conducted at specialized facilities or depots, where highly skilled technicians and specialized equipment are available. Depot maintenance ensures that equipment is restored to its original condition and maintains its operational capability.

The inspection status that is affected by the 30 or 90 day inspection is the Home station check. This means that the Home station check needs to be conducted every 30 or 90 days, depending on the specific requirements. This inspection ensures that the aircraft is in proper working condition and meets all necessary safety standards before it can continue its operations.

A time compliance technical order (TCTO) is typically used to announce changes to baseline computer programs that involve software updates. This means that the correct answer is "Software-only."

The correct answer is 14 minutes of the scheduled departure time. This means that a flight is considered to have an on-time departure if it departs within 14 minutes of the scheduled departure time.

The correct answer is "determine if a meeting is the best tool to address the issue." This answer is supported by the fact that the question states "You evaluate the information you have before you call for a meeting." This implies that the purpose of evaluating the information is to determine whether a meeting is the most effective way to address the issue at hand. The other options (identifying speakers, determining attendance, and evaluating parking space) may be necessary steps in planning a meeting, but they are not the primary purpose of evaluating the information.

In the analysis process, one of your responsibilities is to answer the why, how, when, and where questions. This means that you need to provide a thorough understanding of the reasons behind a problem, how it is occurring, when it is happening, and where it is taking place. By addressing these questions, you can ensure that your assessments are objective and specific, providing a comprehensive analysis of the situation at hand.

Base supply uses the rate of cannibalization to indicate depot support. Cannibalization refers to the practice of removing parts from one piece of equipment to repair or maintain another piece of equipment. This rate indicates the extent to which this practice is being utilized in depot support.

Maintenance data is typically arranged in chronological order, which means it is organized based on the time and date of each maintenance activity. This approach allows for easy tracking and analysis of maintenance events over time, making it easier to identify patterns, track performance, and plan future maintenance activities. Descending order, order of importance, and serial number order are not commonly used approaches for arranging maintenance data.

Bar charts are used for comparing groups of data. A bar chart displays data using rectangular bars, where the length of each bar represents the quantity or value of a particular category or group. By comparing the lengths of the bars, it becomes easy to identify and understand the relative differences or similarities between different groups of data. This visual representation helps in analyzing and interpreting data effectively, making it a useful tool for comparing and presenting data in a clear and concise manner.

A written report is a formal way of presenting a special study because it allows for a structured and detailed analysis of the topic. It provides a comprehensive and organized overview of the study, including the research methodology, findings, and conclusions. A written report also allows for referencing and citation of sources, ensuring credibility and accuracy. Additionally, it can be easily shared and distributed among stakeholders for further review and reference. Overall, a written report is a professional and formal medium that effectively presents a special study.

Off-equipment, operating command refers to the maintenance tasks that can be performed by a unit using their skills and equipment, but not directly on the end item. This means that the maintenance tasks are done on components or systems that are removed from the end item for repair or replacement. This category allows units to carry out necessary maintenance without having to rely on external support or higher-level maintenance organizations.

There are three authorized basic Time Compliance Technical Order (TCTO) categories.

Attrition represents a historical percentage of scheduled sorties lost to causes outside of unit control. This factor reflects the number of sorties that were unable to be completed due to various reasons such as equipment failure, weather conditions, or other unforeseen circumstances. It is an important factor to consider when analyzing the effectiveness and efficiency of a unit's operations.

When an aircraft lands with a code 3 landing status, it means that the aircraft is not mission capable. Therefore, the maintenance status code entered in Integrated Maintenance Data System (IMDS) would be "Not mission capable (NMC)".

People who missed the meeting can find a summary by obtaining a copy of the minutes. Minutes refer to the written record of the discussions, decisions, and actions taken during a meeting. They provide a comprehensive overview of what occurred and are often distributed to attendees and those who were unable to attend. By obtaining a copy of the minutes, individuals can stay informed about what was discussed and any important outcomes or decisions made during the meeting.

By consolidating feasible cannibalizations to a few aircraft when practical, maintenance can keep the Total not mission capable supply (TNMCS) rate low. This means that by using parts from non-mission capable aircraft to repair others, the supply of spare parts is maintained, reducing the number of aircraft that are not mission capable due to lack of necessary supplies.

To determine if you should retain an office copy of a report, you need to consider if there is a real need for the data. This means evaluating whether the information in the report is relevant and useful for current or future purposes. If there is no legitimate reason to keep the data, it can be discarded. Retaining reports solely based on the publication of a new version or a specific time limit (such as one year) may not be practical or necessary if there is no actual need for the information.

A histogram is a type of chart that can be used together with a frequency polygon in frequency distribution. A frequency polygon is a line graph that displays the frequency of data points in a distribution. A histogram, on the other hand, displays the frequency of data points in intervals or bins. By using a histogram alongside a frequency polygon, one can visualize the distribution of data more effectively and accurately. This combination allows for a better understanding of the shape and pattern of the data.

Symbolic shapes and arrows are commonly used in flowcharts to represent different steps and connections in a process. Flowcharts are visual representations that depict the flow of information or activities in a systematic manner. They are used to illustrate the sequence of steps or decisions in a process, making it easier to understand and analyze. Control charts, scatter diagrams, and cause and effect diagrams may also use symbols and arrows, but they are typically more specific to certain types of data analysis or problem-solving techniques. Therefore, the most appropriate answer is flowchart.

The authorized types of time compliance technical orders (TCTOs) are immediate, routine, and urgent. Immediate TCTOs are issued for conditions that could result in injury or loss of life if not corrected immediately. Routine TCTOs are issued for conditions that could result in injury or damage to equipment if not corrected within a specified time frame. Urgent TCTOs are issued for conditions that could result in injury or damage to equipment if not corrected within a specified time frame, but the urgency is not as immediate as for immediate TCTOs.

MTTR stands for Mean Time to Repair, which is a measure of the average time it takes to repair a system or equipment after a failure. Since time is being measured, the correct unit for expressing MTTR is hours.

The correct answer is Twelve. This means that for all aircraft other than fighters, the fix rate time interval reported is twelve. This indicates that these aircraft have a specific time interval at which they are fixed or maintained. The question is asking for the duration of this fix rate time interval, and the correct answer is twelve.

When you track the average elapsed time between a piece of communications-electronics (C-E) equipment going down from partial mission capable (PMC) condition and its being restored to PMC condition, you are measuring the downtime. This refers to the period of time during which the equipment is not functioning or is in a state of partial capability. It is the time taken to repair or restore the equipment to its full operational state.

The correct answer is Maintenance Management Analysis. The Integrated Maintenance Data System (IMDS) Users' Group meetings are chaired by the Maintenance Management Analysis. This individual is responsible for overseeing and analyzing the maintenance management processes and data within the organization. They play a key role in ensuring the effectiveness and efficiency of the maintenance operations.

The Integrated Maintenance Data System (IMDS) downtime does not affect equipment downtime because it is a system used for managing and tracking maintenance activities. It does not directly impact the actual functioning or availability of the equipment. Manning level, experience level, and support equipment availability, on the other hand, can all have an impact on equipment downtime.

A repeat discrepancy occurs after one sortie following the original problem report.

When you are establishing the scope of your special study, you are defining your assumptions and limitations. This means that you are specifying the boundaries and constraints of your research, including any assumptions you are making about the subject matter and any limitations on the data or methods you will use. This step is important in order to ensure the validity and reliability of your study and to manage expectations about what you can realistically achieve within the given scope.

Weights are usually assigned when computing maintenance scheduling effectiveness rates to show the degree of importance of a task. This means that certain tasks may be considered more critical or crucial than others, and therefore, they are given a higher weight in the calculation of the effectiveness rate. By assigning weights, the scheduling process can prioritize and focus on the most important tasks, ensuring that they are completed efficiently and effectively.

The command that uses the departure reliability rate is the Air Mobility Command (AMC). This command is responsible for providing air transportation and aerial refueling capabilities to support global mobility operations. The departure reliability rate is a measure of how often aircraft depart on time, which is crucial for ensuring efficient and effective transportation of personnel and cargo.

The correct answer is sortie and hourly. Utilization (UTE) rate can be computed using two methods: sortie and hourly. The sortie method calculates the utilization rate based on the number of sorties (flights) completed within a specific period of time. The hourly method calculates the utilization rate based on the number of hours the equipment or aircraft is in use. Both methods provide different perspectives on the utilization of resources and can be used to analyze and manage the efficiency of operations.

The spare factor is determined by comparing the number of 1st sortie logistics losses to the number of historical sorties scheduled. This comparison helps to assess the effectiveness of the logistics system in minimizing losses and ensuring that an adequate number of spare aircraft are available for future sorties.

The correct answer is mission-essential system functions. The communications-electronics (C-E) mean time between critical failure (MTBCF) specifically measures the average operating time between system failures of mission-essential system functions. This means that it focuses on the functions that are crucial for the mission's success and reliability. It does not include ground-based system functions, aircraft-related system functions, or all base support system functions, as these may not necessarily be directly related to the mission's essential operations.

The correct answer is "air and ground abort." This means that the total abort rate includes both air aborts and ground aborts. Air abort refers to a situation where an aircraft has to abort its takeoff or landing due to a technical issue or safety concern. Ground abort, on the other hand, refers to an abort that occurs before the aircraft even takes off, such as when there is a problem with the aircraft on the ground. By including both air and ground aborts in the total abort rate, a comprehensive picture of the number of aborts can be obtained.

The objective of the phased inspection concept is to minimize the length of time that an aircraft is out of commission due to a scheduled inspection. This means that the phased inspection concept is designed to efficiently and effectively carry out inspections on an aircraft while minimizing the impact on its operational availability.

All aircraft, regardless of the inspection concept applied, are required to have two calendar inspections. This means that there are specific intervals of time in which these inspections must be conducted to ensure the safety and proper functioning of the aircraft. These inspections are necessary to identify any potential issues or maintenance needs that may arise over time.

The correct answer is Total not mission capable supply (TNMCS). This mission capability status code reflects the total number of aircraft that are not mission capable due to supply issues. It includes both not mission capable supply (NMCS) and not mission capable both (NMCB) aircraft limitations. This code indicates that the aircraft cannot perform its mission due to supply-related problems.

The correct answer is "arrives at the equipment." This means that the mean repair time (MRT) starts when the technician reaches the equipment that needs to be repaired. This makes sense because the technician cannot begin the repair process until they are physically present at the equipment. The MRT does not include the time it takes for the technician to travel to the equipment or receive notification of a workorder. The MRT specifically focuses on the time it takes for the technician to repair the equipment once they have arrived at the location.

The fix rate is used to measure the speed of repair and equipment maintainability. It refers to the rate at which repairs are made to equipment or machinery when they break or malfunction. A higher fix rate indicates that repairs are being done quickly and efficiently, resulting in less downtime and improved equipment availability.

The Logistics, Installations and Mission Support–Enterprise View (LIMS–EV) has the capability to support strategic, operational, and tactical level users. This means that the system can provide support and information to users at all levels of decision-making within an organization. Strategic level users are responsible for long-term planning and decision-making, operational level users are responsible for day-to-day operations and management, and tactical level users are responsible for executing specific tasks and operations. Therefore, the LIMS–EV system can cater to the needs of users across all these levels.
