ASI - Aviation Safety Inspector Maintenance and Repair Procedures Questions and Answers 1 — Questions and Answers
Question 1: An aircraft undergoes a modification that is not listed in the aircraft specifications, and if improperly performed, might appreciably affect its weight, balance, and structural strength. How must this work be recorded?
- In the aircraft's maintenance logbook with a signature from a certified mechanic.
- On an FAA Form 337, which becomes a permanent part of the aircraft's records. (Correct answer)
- By making an entry in the airframe logbook and notifying the local FSDO.
- On a work order from a certificated repair station, kept on file for one year.
Correct answer: On an FAA Form 337, which becomes a permanent part of the aircraft's records.
According to 14 CFR Part 43, a major alteration, such as one affecting weight, balance, or structural strength, must be documented on FAA Form 337. This form provides a detailed record of the work performed and the data used for approval, and it becomes a permanent part of the aircraft's maintenance records.
Question 2: A certificated 14 CFR Part 145 Repair Station must have a Repair Station Manual (RSM) that is acceptable to the FAA. Which of the following is a required element of the RSM?
- A list of all employees and their home addresses.
- A copy of the repair station's business license.
- Procedures for maintaining and revising the list of maintenance functions to be contracted to other persons. (Correct answer)
- The fee schedule for all maintenance work performed at the facility.
Correct answer: Procedures for maintaining and revising the list of maintenance functions to be contracted to other persons.
14 CFR § 145.207 mandates that a certificated repair station must prepare and follow an FAA-acceptable Repair Station Manual. This manual must include procedures for maintaining and revising the list of maintenance functions contracted to other facilities, which also requires FAA approval.
Question 3: An Aviation Safety Inspector is reviewing the maintenance records for an aircraft. For which of the following items must the records be retained and transferred with the aircraft when it is sold?
- Records of the last 100-hour inspection.
- The current status of life-limited parts. (Correct answer)
- Records of compliance with a non-recurring Airworthiness Directive (AD).
- Records of preventive maintenance performed by the owner/operator.
Correct answer: The current status of life-limited parts.
According to 14 CFR § 91.417(a)(2), records detailing the current status of life-limited parts of the airframe, each engine, propeller, rotor, and appliance must be retained and transferred with the aircraft upon its sale. Records of the last 100-hour inspection and preventive maintenance are typically kept for one year or until the work is repeated or superseded.
Question 4: Which of the following tasks is considered preventive maintenance that can be performed by a person who holds at least a private pilot certificate on an aircraft owned or operated by them, provided it is not used in air carrier service?
- The repair of a main landing gear strut.
- An annual inspection under Part 91.
- The overhaul of a propeller governor.
- Replacing defective safety wiring or cotter keys. (Correct answer)
Correct answer: Replacing defective safety wiring or cotter keys.
14 CFR Part 43, Appendix A, Section (c) lists the tasks that are considered preventive maintenance. Replacing defective safety wiring or cotter keys is explicitly listed as a preventive maintenance task that a pilot can perform on their own aircraft, as long as it does not involve complex assembly operations. The other options are considered either major repairs or required inspections that demand a higher level of certification to perform.
Question 5: A maintenance technician is performing a repair on an aircraft's wing spar. The manufacturer's maintenance manual does not provide specific instructions for this type of repair. Which document should the technician consult for acceptable methods, techniques, and practices for the repair?
- The aircraft's Type Certificate Data Sheet (TCDS).
- Advisory Circular (AC) 43.13-1B. (Correct answer)
- The Pilot's Operating Handbook (POH).
- 14 CFR Part 21 - Certification Procedures for Products and Parts.
Correct answer: Advisory Circular (AC) 43.13-1B.
Advisory Circular (AC) 43.13-1B, 'Acceptable Methods, Techniques, and Practices - Aircraft Inspection and Repair,' provides guidance for repairs when no manufacturer's instructions are available. This AC contains information on various repairs for non-pressurized aircraft structures and is considered acceptable data by the FAA.
Question 6: A person working under the supervision of a certificated mechanic performs a maintenance task. According to 14 CFR § 43.3, what is a key requirement for this supervised work to be permissible?
- The supervising mechanic must be in the same hangar as the person performing the work.
- The supervisor must personally observe the work to the extent necessary to ensure it is being done properly and be readily available for consultation. (Correct answer)
- The person performing the work must have completed a certified aviation maintenance training program.
- The supervisor can delegate the final inspection and approval for return to service to the person who performed the work.
Correct answer: The supervisor must personally observe the work to the extent necessary to ensure it is being done properly and be readily available for consultation.
14 CFR § 43.3(d) states that a person may perform maintenance under the supervision of a certificated mechanic if the supervisor personally observes the work as needed to ensure it's done correctly and is readily available, in person, for consultation. However, this does not authorize the supervised person to perform required inspections, such as an inspection after a major repair.
