Questions and Answers
  • 1. 

    What are the two classifications of failures in RCM?

    • A.

      Potential and functional.

    • B.

      Potential and evident.

    • C.

      Hidden and Functional.

    • D.

      Evident and hidden.

    Correct Answer
    A. Potential and functional.
    Explanation
    The two classifications of failures in RCM are potential and functional. Potential failures refer to the failures that have not yet occurred but have the potential to happen in the future. These failures are identified through analysis and proactive measures are taken to prevent them. On the other hand, functional failures are the failures that have already occurred and are affecting the system's performance or functionality. These failures are usually addressed through reactive maintenance measures.

    Rate this question:

  • 2. 

    In RCM,which preventative maintenance task is a scheduled inspection to detect a potential failure condition?

    • A.

      Lubrication.

    • B.

      On condition.

    • C.

      Failure finding.

    • D.

      Hard time.

    Correct Answer
    B. On condition.
    Explanation
    On condition maintenance is a scheduled inspection to detect a potential failure condition in RCM. This type of maintenance involves monitoring the equipment's condition and performing inspections or tests to identify any signs of deterioration or potential failure. By detecting these conditions early on, maintenance can be performed proactively to prevent the failure from occurring and ensure the equipment's reliability and performance.

    Rate this question:

  • 3. 

    The primary goal of the ET&D program is to prevent or limit damage to turbine engines by

    • A.

      Reviewing past engine accident investigation reports.

    • B.

      Traking serially controlled components and modules.

    • C.

      Early detection of performance degradation and/or failures.

    • D.

      Documenting engine overspeed and overtemperature conditions.

    Correct Answer
    C. Early detection of performance degradation and/or failures.
    Explanation
    The primary goal of the ET&D program is to detect performance degradation and/or failures early on. This helps in preventing or limiting damage to turbine engines. By reviewing past engine accident investigation reports, tracking serially controlled components and modules, and documenting engine overspeed and overtemperature conditions, the program can identify potential issues and take necessary actions to ensure the engines are functioning optimally. However, the main focus is on early detection to address any performance degradation or failures promptly and minimize damage.

    Rate this question:

  • 4. 

    Within the ET&D, to whom do flightline personnel transfer collected data for analysis?

    • A.

      Base engine maintenance shop.

    • B.

      Depot-level engine maintenance shops.

    • C.

      Product center engineers.

    Correct Answer
    A. Base engine maintenance shop.
    Explanation
    Flightline personnel transfer collected data for analysis to the Base engine maintenance shop. This is because the Base engine maintenance shop is responsible for conducting maintenance and repairs on aircraft engines at the base level. They have the expertise and resources to analyze the collected data and make informed decisions regarding engine maintenance and performance. Depot-level engine maintenance shops and product center engineers may also be involved in engine maintenance, but the primary transfer of data for analysis is to the Base engine maintenance shop.

    Rate this question:

  • 5. 

    Which technicians provide maintenance activity data to the ET&D program?

    • A.

      Propulsion and depot.

    • B.

      Depot and nondestructive inspection.

    • C.

      Propulsion and nondestructive inspection.

    • D.

      Environmental health and nondestructive inspection.

    Correct Answer
    C. Propulsion and nondestructive inspection.
    Explanation
    Propulsion and nondestructive inspection technicians are responsible for providing maintenance activity data to the ET&D program. They play a crucial role in ensuring that the propulsion systems are properly maintained and inspected for any potential issues. Additionally, nondestructive inspection technicians are trained to use various techniques to detect and evaluate defects or abnormalities in materials or components without causing damage. By providing accurate and timely maintenance activity data, these technicians contribute to the overall efficiency and safety of the ET&D program.

    Rate this question:

  • 6. 

    What drives the creation of a CRP?

    • A.

      Customer wait time and transportation constraints.

    • B.

      Number of assigned maintenance personnel.

    • C.

      Number of available spare engines.

    • D.

      Equipment cost and repair time.

    Correct Answer
    A. Customer wait time and transportation constraints.
    Explanation
    The creation of a CRP (Critical Resource Plan) is driven by customer wait time and transportation constraints. This means that when customers have to wait for a long time to receive a product or service, or when there are limitations in transporting goods or resources, a CRP is created to address these issues and ensure efficient operations. The other options mentioned, such as the number of assigned maintenance personnel, number of available spare engines, and equipment cost and repair time, may be important factors in other contexts but are not directly related to the creation of a CRP.

    Which is not a Lead the Fleet/Pacer program objective?

    • A.

      Reducing customer wait time for serviceable assets.

    • B.

      Accurately update scheduled maintenance requirements.

    • C.

      Beer

    Correct Answer
    A. Reducing customer wait time for serviceable assets.
    Explanation
    The objective of the Lead the Fleet/Pacer program is to accurately update scheduled maintenance requirements, which helps in ensuring that assets are properly maintained and serviced. However, reducing customer wait time for serviceable assets is not specifically mentioned as an objective of the program. This suggests that the program may not focus on this particular aspect and instead prioritizes other objectives related to maintenance and asset management. The option "beer" is not a valid objective and can be disregarded.
