Which document represents recognized standards for aviation maintenance practices?

The correct choice highlights AC 43.13-2A as a crucial document that lays out recognized standards for aviation maintenance practices. This advisory circular provides comprehensive guidelines and best practices for repairing and maintaining aircraft, ensuring safety and compliance with regulatory requirements.

AC 43.13-2A serves as a key resource for maintenance personnel, detailing acceptable methods, techniques, and practices that promote airworthiness. Its authority derives from being recognized by the FAA, which emphasizes the importance of following these standards to uphold safety in aviation operations.

In contrast, while FAA Airworthiness Directives are critical for addressing specific safety issues with particular aircraft or components, they are not broad standards but rather directives focused on compliance with specific safety requirements. The Technical Manual of Aeronautics may contain relevant information, but it does not establish the recognized standards that AC 43.13-2A does. Similarly, a Standard Operating Procedure Manual is more organization-specific and may not align with the universal standards necessary for aviation maintenance practices.
