1. An Inspection Authorization (IA) holder is preparing to perform an annual inspection on a
turbine-powered aircraft operated under Part 91. Which maintenance record entry is required
before returning the aircraft to service?
A. A statement that the aircraft was inspected in accordance with manufacturer
recommendations only
B. A statement approving the aircraft for return to service after an annual inspection
C. A list of discrepancies only, regardless of airworthiness status
D. A maintenance release signed by the aircraft owner only
════════════════════
Correct Answer: B. A statement approving the aircraft for return to service after an annual
inspection
Rationale:
An annual inspection requires a maintenance record entry stating that the aircraft has been
inspected in accordance with an annual inspection and was determined to be airworthy
before return to service. A discrepancy list alone is insufficient unless the aircraft is not
approved for return to service. Manufacturer recommendations do not replace regulatory
inspection requirements, and the owner cannot authorize return to service independently.
════════════════════
2. During a progressive inspection, an IA discovers corrosion on a primary structural member
that exceeds allowable limits. What is the most appropriate action?
A. Defer the discrepancy until the next inspection cycle
B. Apply corrosion inhibitor and continue operations
C. Remove the aircraft from service until corrective action is completed
D. Record the discrepancy only if requested by the owner
════════════════════
Correct Answer: C. Remove the aircraft from service until corrective action is completed
,Rationale:
Structural corrosion exceeding allowable limits affects airworthiness and must be corrected
before further flight unless properly deferred under an approved procedure. Corrosion
inhibitor alone does not restore structural integrity, and owner preference does not override
regulatory compliance.
════════════════════
3. Which document provides FAA-approved procedures for major repairs and alterations
when manufacturer data is unavailable?
A. Airworthiness Directives
B. Advisory Circular 43.13-1B
C. Minimum Equipment List
D. Aircraft Flight Manual
════════════════════
Correct Answer: B. Advisory Circular 43.13-1B
Rationale:
AC 43.13-1B contains FAA-accepted methods, techniques, and practices for aircraft inspection
and repair when no manufacturer-approved data exists. Airworthiness Directives mandate
corrective actions, while MELs and AFMs serve different operational purposes.
════════════════════
4. An IA signs off a major alteration using FAA Form 337. Which additional action is normally
required?
A. Submit the form only to the aircraft owner
B. Destroy previous maintenance records related to the alteration
C. Forward a completed copy to the FAA within the required timeframe
D. Notify the aircraft manufacturer before flight operations resume
════════════════════
Correct Answer: C. Forward a completed copy to the FAA within the required timeframe
Rationale:
FAA Form 337 for major repairs or alterations must be completed and a copy submitted to the
FAA Aircraft Registration Branch within the required period. Maintenance records must be
retained, and manufacturer notification is generally not mandatory unless specified.
,════════════════════
5. While reviewing logbooks, an IA notices an overdue Airworthiness Directive (AD). What
should the IA do before approving the aircraft for return to service?
A. Ignore the AD if the aircraft owner accepts responsibility
B. Verify compliance with the AD or ensure the aircraft is not returned to service
C. Make a note to comply during the next inspection cycle
D. Return the aircraft to service with operational limitations only
════════════════════
Correct Answer: B. Verify compliance with the AD or ensure the aircraft is not returned to
service
Rationale:
Compliance with applicable Airworthiness Directives is mandatory for airworthiness. An
aircraft with an overdue AD cannot legally be approved for return to service unless a proper
exemption or approved alternative method of compliance exists.
════════════════════
6. Which of the following best describes the purpose of a conformity inspection?
A. To determine pilot competency during maintenance flights
B. To evaluate fuel efficiency trends
C. To ensure an aircraft or component matches approved design data
D. To validate airport operational procedures
════════════════════
Correct Answer: C. To ensure an aircraft or component matches approved design data
Rationale:
Conformity inspections verify that aircraft components, installations, or modifications
conform to approved engineering and design specifications. They are essential in maintaining
regulatory compliance and airworthiness standards.
════════════════════
7. An IA is inspecting an aircraft with a recurring oil leak after multiple repairs. What is the
best professional approach?
A. Continue replacing seals without troubleshooting
B. Recommend grounding the aircraft permanently
, C. Document the issue and release the aircraft without further action
D. Conduct a systematic root-cause analysis before approving return to service
════════════════════
Correct Answer: D. Conduct a systematic root-cause analysis before approving return to
service
Rationale:
Recurring discrepancies require thorough troubleshooting to identify underlying causes.
Repeatedly replacing parts without diagnosis may overlook a systemic problem and
compromise safety. Proper investigative maintenance reflects professional and regulatory
standards.
════════════════════
8. What is the primary purpose of an Airworthiness Directive?
A. To provide optional maintenance guidance
B. To recommend improved operational efficiency
C. To mandate corrective action for unsafe conditions
D. To establish pilot currency requirements
════════════════════
Correct Answer: C. To mandate corrective action for unsafe conditions
Rationale:
Airworthiness Directives are legally enforceable regulations issued to correct unsafe
conditions in aircraft, engines, propellers, or appliances. Compliance is mandatory unless an
approved alternative method exists.
════════════════════
9. Which inspection may be substituted for an annual inspection on certain aircraft operated
under Part 91?
A. 100-hour inspection only
B. Progressive inspection
C. Ramp inspection
D. Pitot-static inspection
════════════════════
Correct Answer: B. Progressive inspection
