Airworthiness Directives; American General Aircraft Corporation Models AA-5, AA-5A, AA-5B, and AG-5B Airplanes

Abstract

This document proposes to adopt a new airworthiness directive (AD) that would apply to American General Aircraft Corporation (American General) Models AA-5, AA-5A, AA-5B, and AG-5B airplanes. The proposed action would require inspecting (one-time) the wing attach shoulder bolts for fretting, scoring, wear, excessive clearance, or enlarged or elongated mounting holes (known as damage from hereon), replacing any damaged parts and repairing any damaged areas, and reporting to the Federal Aviation Administration (FAA) the results of the inspection. Four reports of wing attach shoulder bolt failure prompted the proposed action. The actions specified by the proposed AD are intended to prevent wing attach shoulder bolt failure, which could lead to structural damage of the wing/fuselage to the point of failure.
