1. Which document provides the primary guidance for maintenance
procedures on certified aircraft?
A. Aircraft Flight Manual
B. Maintenance Planning Document
C. Federal Aviation Administration (FAA) Advisory Circulars
D. Aircraft Registration Certificate
Advisory Circulars issued by the FAA provide standardized guidance
and recommended practices for aircraft maintenance, ensuring
compliance with federal regulations.
2. What is the primary purpose of an Airworthiness Directive (AD)?
A. To suggest modifications to enhance comfort
B. To regulate pilot certifications
C. To mandate corrective actions for known unsafe conditions
D. To provide maintenance tips for aircraft owners
Airworthiness Directives are legally enforceable regulations issued by
the FAA to correct unsafe conditions in aircraft, engines, or
components.
3. During a maintenance inspection, a crack is discovered in a critical
structural component. What is the inspector's primary responsibility?
A. Notify the pilot for further action
B. Document and schedule repair at convenience
C. Ensure immediate compliance with FAA-approved repair
, procedures
D. Ignore if the crack is minor
Inspectors must ensure safety by enforcing compliance with
approved repair procedures, as cracks in critical structures can
compromise airworthiness.
4. Which inspection is required after a specific number of flight hours or
calendar time to ensure continued airworthiness?
A. Preflight Check
B. Routine Visual Check
C. Periodic/Recurring Inspection
D. Ramp Check
Periodic inspections are mandated at set intervals to detect and
correct wear, corrosion, or fatigue, ensuring aircraft remain
airworthy.
5. In the context of maintenance, what does MEL stand for?
A. Mandatory Equipment List
B. Maintenance Equipment Log
C. Minimum Equipment List
D. Mechanical Evaluation Level
The Minimum Equipment List defines the equipment that must be
operational for the aircraft to be considered airworthy and allowed
to operate.
6. Which type of maintenance involves replacing parts before failure
occurs?
A. Corrective Maintenance
B. Emergency Maintenance
C. Preventive Maintenance
D. Scheduled Inspection
Preventive maintenance proactively replaces or services components
to avoid unexpected failures and maintain operational safety.
7. Which tool is essential for detecting hidden cracks or defects in
metallic aircraft structures?
A. Torque Wrench
B. Hydraulic Jack
C. Non-Destructive Testing (NDT) equipment
, D. Vernier Caliper
NDT methods such as ultrasonic or eddy current testing allow
inspectors to detect internal flaws without damaging the structure.
8. What is the primary focus of corrosion control programs in aviation
maintenance?
A. Improving fuel efficiency
B. Reducing noise levels
C. Preventing structural deterioration and ensuring safety
D. Enhancing cabin aesthetics
Corrosion can compromise structural integrity, so corrosion control
programs protect safety and longevity of aircraft components.
9. Which maintenance record is legally required for each aircraft part
installed?
A. Owner’s Manual
B. Maintenance Log Summary
C. Form 8130-3 or equivalent FAA-approved documentation
D. Warranty Certificate
FAA Form 8130-3 certifies that a part meets airworthiness standards
and is traceable to approved sources.
10. When performing a functional check of an aircraft system after
maintenance, what is the inspector verifying?
A. The aesthetic appearance of components
B. Pilot preference compliance
C. Proper operation and performance of the system according to
standards
D. Fuel consumption rates
Functional checks ensure that systems perform safely and as
intended after maintenance or repair.
11. What is the purpose of a Service Bulletin issued by an aircraft
manufacturer?
A. To document flight schedules
B. To regulate pilot licensing
C. To provide recommended maintenance actions or improvements
D. To enforce FAA regulations
Service Bulletins inform operators about improvements or known
