BAvn Bachelor of Aviation Bachelor of Aviation Maintenance Management 5 — Questions and Answers
Question 1: In aviation supply chain management, what does the term 'traceability' specifically require for aircraft parts?
- That all parts be purchased from the OEM only
- That each part can be traced back to an FAA-approved source with documented history (Correct answer)
- That inventory is tracked via barcode in real time
- That parts are inspected every 90 days regardless of installation status
Correct answer: That each part can be traced back to an FAA-approved source with documented history
Traceability requires documented evidence linking a part to its approved manufacturer, certification basis, and maintenance history throughout its service life.
Question 2: What is the purpose of a 'critical design configuration control limitation' (CDCCL) in aircraft maintenance?
- To limit the number of modifications allowed on a single aircraft
- To protect design features essential to fuel tank flammability reduction (Correct answer)
- To establish maximum weight limits for cargo configurations
- To restrict maintenance to OEM-trained technicians only
Correct answer: To protect design features essential to fuel tank flammability reduction
CDCCLs were introduced post-TWA 800 to identify and protect design features critical to fuel tank safety that must never be altered.
Question 3: A Part 121 airline's Director of Maintenance (DOM) discovers that a contracted MRO performed unauthorized maintenance. Who bears primary regulatory responsibility?
- The MRO's accountable manager
- The airline as the certificate holder (Correct answer)
- The individual technician who performed the work
- The FAA Principal Maintenance Inspector
Correct answer: The airline as the certificate holder
Under 14 CFR Part 121, the air carrier retains full regulatory responsibility for all maintenance, even when contracted to a third-party MRO.
Question 4: Which technique is used in non-destructive testing (NDT) to detect subsurface cracks in ferromagnetic aircraft components?
- Dye penetrant inspection
- Magnetic particle inspection (Correct answer)
- Ultrasonic testing
- Eddy current testing
Correct answer: Magnetic particle inspection
Magnetic particle inspection detects surface and near-surface discontinuities in ferromagnetic materials by revealing disruptions in a magnetic field.
Question 5: In aviation maintenance resource management (MRM), the concept of 'assertiveness' training is intended to address what specific issue?
- Motivating technicians to work faster under time pressure
- Empowering junior personnel to raise safety concerns without fear of reprisal (Correct answer)
- Teaching supervisors to enforce discipline more effectively
- Training inspectors to challenge engineering decisions
Correct answer: Empowering junior personnel to raise safety concerns without fear of reprisal
Assertiveness training in MRM helps all team members, especially junior ones, speak up about safety concerns even when authority gradients might suppress communication.
Question 6: What distinguishes a 'major repair' from a 'minor repair' under 14 CFR Part 43?
- The cost of parts and labor involved
- Whether the repair might appreciably affect structural strength, flight characteristics, or other airworthiness qualities (Correct answer)
- Whether the aircraft is operated under Part 91 or Part 121
- Whether the repair requires removal of a major component
Correct answer: Whether the repair might appreciably affect structural strength, flight characteristics, or other airworthiness qualities
A major repair is one that, if improperly done, might appreciably affect the aircraft's structural strength, flight characteristics, or other airworthiness properties.
Question 7: In the context of aviation maintenance scheduling, what is the primary advantage of 'block maintenance' over 'line maintenance'?
- Block maintenance is cheaper per task because it requires fewer tools
- Block maintenance consolidates multiple tasks during planned downtime, reducing total aircraft-out-of-service time (Correct answer)
- Block maintenance allows unapproved technicians to perform inspections
- Block maintenance eliminates the need for an approved maintenance program
Correct answer: Block maintenance consolidates multiple tasks during planned downtime, reducing total aircraft-out-of-service time
By batching multiple maintenance tasks into a single downtime event, block maintenance minimizes the cumulative time an aircraft is removed from revenue service.
