Which document should be consulted to determine skin-area strength replacement requirements?

Which document should be consulted to determine skin-area strength replacement requirements?

• A. Aircraft Structural Repair Manual (SRM)
• B. Maintenance Manual (MM)
• C. Airworthiness Directive (AD)
• D. Operator's Handbook

Answer: (A)

This question focuses on where the official repair data for structural components are found, including when skin areas must be replaced or reinforced. The Aircraft Structural Repair Manual contains the approved repair data for airframe structures, including skin panels. It provides the exact criteria for when skin damage can be repaired, how large a damaged area can be, what kind of patch or doubler is required, fastener patterns, materials, and any necessary reinforcement to restore the original strength and load path. Because these repair details are approved to maintain airworthiness, the SRM is the primary reference an AMT uses to determine skin-area strength replacement requirements. A Maintenance Manual covers general maintenance tasks and procedures, not the specific structural repair limits and methods. An Airworthiness Directive is a regulatory directive addressing a specific unsafe condition with mandated actions, but it does not serve as the general reference for routine skin repair criteria. The Operator's Handbook is for flight crew procedures and is not a source of repair data.
