AMT FAA Regulations and Publications Questions and Answers 1 — Questions and Answers
Question 1: An aircraft is subject to a new Airworthiness Directive (AD) that mandates a specific inspection "within the next 100 hours of time-in-service." What is the regulatory status of this AD?
- The AD is a recommendation and can be deferred until the next annual inspection.
- The AD is mandatory and must be complied with before the next flight, regardless of the time limit.
- The AD is mandatory and must be complied with as specified to maintain the aircraft's airworthiness. (Correct answer)
- The AD is optional for private operators but mandatory for commercial operators.
Correct answer: The AD is mandatory and must be complied with as specified to maintain the aircraft's airworthiness.
According to 14 CFR Part 39, Airworthiness Directives are legally enforceable rules issued by the FAA to correct an unsafe condition. Compliance is mandatory within the timeframe specified in the AD (e.g., hours, cycles, or calendar time) for the aircraft to remain airworthy.
Question 2: According to 14 CFR Part 43.9, which of the following is required to be included in a maintenance record entry after performing a repair?
- The total time-in-service of the airframe.
- The signature, certificate number, and kind of certificate held by the person approving the work. (Correct answer)
- The part numbers of all components that were replaced.
- The date the next required inspection is due.
Correct answer: The signature, certificate number, and kind of certificate held by the person approving the work.
14 CFR 43.9 explicitly requires that a maintenance record entry contain: a description of the work, the date of completion, and if the work was performed satisfactorily, the signature, certificate number, and kind of certificate held by the person approving the work for return to service. Total time-in-service is required for inspection entries under 43.11, not general maintenance entries under 43.9.
Question 3: A technician needs to find the official, FAA-certified specifications for an engine, including its maximum power rating, approved fuel grades, and specific operating limitations. Which document is the primary source for this information?
- Advisory Circular 43.13-1B
- The aircraft's maintenance manual
- The engine's Type Certificate Data Sheet (TCDS) (Correct answer)
- The Code of Federal Regulations, Part 43
Correct answer: The engine's Type Certificate Data Sheet (TCDS)
The Type Certificate Data Sheet (TCDS) is an FAA document that provides a formal description of the aircraft, engine, or propeller. It contains the essential data required for certification, such as operating limitations, required placards, control surface travel, and engine/propeller combinations.
Question 4: A technician performs a structural repair to a wing spar, which involved splicing a new section of material. According to 14 CFR Part 43, Appendix A, how must this work be classified and recorded?
- As a major repair, requiring an entry on FAA Form 337. (Correct answer)
- As a minor repair, requiring only a standard logbook entry.
- As preventive maintenance, which can be signed off by a private pilot.
- As a major alteration, requiring a Supplemental Type Certificate (STC).
Correct answer: As a major repair, requiring an entry on FAA Form 337.
14 CFR Part 43, Appendix A defines major repairs. Repairs to primary structural members like spars, involving strengthening or splicing, are explicitly listed as airframe major repairs. Major repairs must be recorded on an FAA Form 337 in addition to a standard logbook entry.
Question 5: Which of the following best describes the nature and legal force of FAA Advisory Circulars (ACs)?
- They are legally binding regulations that must be followed by all aviation personnel.
- They are temporary rules issued by the FAA that expire after one year.
- They are non-regulatory publications that provide guidance and acceptable methods for complying with regulations, but are not binding unless incorporated into a regulation. (Correct answer)
- They are documents used exclusively to publish and track Airworthiness Directives.
Correct answer: They are non-regulatory publications that provide guidance and acceptable methods for complying with regulations, but are not binding unless incorporated into a regulation.
The FAA issues Advisory Circulars (ACs) to provide guidance and information on various subjects. Unless a specific AC is incorporated by reference into a regulation (a part of the CFRs), its content is not legally binding and represents an acceptable, but not exclusive, means of compliance.
Question 6: Regarding annual and 100-hour inspections, which statement accurately reflects the privileges of an A&P mechanic versus an A&P with Inspection Authorization (IA)?
- Any A&P mechanic may perform both annual and 100-hour inspections.
- An A&P mechanic may perform a 100-hour inspection, but an annual inspection requires an A&P with an IA. (Correct answer)
- Both inspection types require the mechanic to hold an Inspection Authorization (IA).
- An A&P mechanic can perform an annual inspection, but a 100-hour inspection must be done at a certified repair station.
Correct answer: An A&P mechanic may perform a 100-hour inspection, but an annual inspection requires an A&P with an IA.
According to 14 CFR 91.409, a 100-hour inspection may be performed by a certified A&P mechanic. However, an annual inspection, which can substitute for a 100-hour inspection, must be performed by an A&P mechanic who also holds an Inspection Authorization (IA).
