An aircraft maintenance record entry for a completed repair must include which of the following?
ACS code: AM.I.I
Correct answer: A description of the work, the date, and the signature and certificate number of the person approving return to service
Rationale: Under 14 CFR 43.9, a maintenance record entry for maintenance, preventive maintenance, or alteration must contain a description of the work performed, the date of completion, and the name plus signature and certificate number of the person approving the aircraft for return to service. The owner does not sign off the work, and removed-part serial numbers are not a required element of the basic record entry.
How long must a record of maintenance performed on an aircraft be retained under 14 CFR Part 91?
ACS code: AM.I.I
Correct answer: Until the work is repeated, superseded, or for one year after the work is performed
Rationale: Per 14 CFR 91.417, records of maintenance, preventive maintenance, and alterations must be retained until the work is repeated, superseded by other work, or for one year after the work is performed. The total-time and inspection-status records are kept permanently and transferred with the aircraft, but the individual maintenance record itself follows the one-year rule.
Compliance with an Airworthiness Directive (AD) is the responsibility of the
ACS code: AM.I.I
Correct answer: aircraft owner or operator
Rationale: Under 14 CFR 39 and 91.403, the owner or operator is primarily responsible for maintaining the aircraft in an airworthy condition, which includes ensuring compliance with all applicable Airworthiness Directives. The manufacturer issues service information and the FSDO provides oversight, but neither is responsible for AD compliance on a specific aircraft.
Airworthiness Directives are issued by the FAA primarily to
ACS code: AM.I.I
Correct answer: correct an unsafe condition existing in a product
Rationale: Airworthiness Directives are issued under 14 CFR 39 when an unsafe condition is found to exist in a product and that condition is likely to exist in other products of the same type design. ADs are mandatory and regulatory, unlike manufacturer service bulletins, which are typically recommendations.
The primary purpose of an FAA Advisory Circular (AC) is to
ACS code: AM.I.I
Correct answer: provide guidance and acceptable means of compliance with the regulations
Rationale: Advisory Circulars provide non-regulatory guidance and describe acceptable methods, techniques, and practices for complying with the regulations. They are not themselves binding rules and do not supersede the CFR; an AC presents one acceptable means of compliance rather than a mandatory requirement.
Which publication contains methods, techniques, and practices acceptable to the Administrator for the inspection and repair of nonpressurized civil aircraft?
ACS code: AM.I.I
Correct answer: AC 43.13-1
Rationale: AC 43.13-1 (Acceptable Methods, Techniques, and Practices—Aircraft Inspection and Repair) provides acceptable methods for repairs when no manufacturer data is available, applicable to nonpressurized areas of civil aircraft. AC 65-9 is the general airframe and powerplant handbook reference and AC 20-62 addresses parts eligibility, so neither serves the repair-methods role of AC 43.13-1.
When making a maintenance record entry, an error in the entry should be corrected by
ACS code: AM.I.I
Correct answer: drawing a single line through the error and initialing the change
Rationale: Maintenance records are legal documents, so an error is corrected by drawing a single line through it and initialing, leaving the original entry legible. Erasing or covering an entry with correction fluid destroys the original information and is not acceptable practice for permanent records.
