Which documents typically specify the NDI methods and procedures?

The correct choice highlights documents such as the Aircraft Maintenance Manual (AMM), Structural Repair Manual (SRM), Airworthiness Directives (ADs), Service Bulletins (SBs), and Supplemental Structural Inspection Documents (SSID). These documents collectively serve as authoritative resources that outline the specific non-destructive inspection (NDI) methods and procedures required for various aircraft components and systems.

Each of these documents plays a crucial role in the maintenance and safety protocols of aircraft. The AMM provides detailed instructions on maintenance procedures, including inspection methods. The SRM focuses on structural components and their repair processes. ADs are issued by regulatory authorities to mandate inspections or modifications that ensure continued airworthiness, while SBs provide updates from manufacturers regarding improvements or required inspections. SSIDs outline supplementary inspections that may be necessary for aging aircraft, specifying which NDI methods should be employed.

While manufacturer’s guidelines certainly offer valuable information, they may not encompass all the NDI methods and procedures needed for compliance with safety standards. Safety regulations deal more broadly with operational practices and requirements but do not typically specify inspection methods in the same detailed manner as AMM, SRM, ADs, SBs, and SSIDs. Inspection reports, on the other hand, document the results of inspections
