Airworthiness Directives; The Don Luscombe Aviation History Foundation Model 8 Series Airplanes.

摘要

This document proposes to adopt a new airworthiness directive (AD) that would apply to The Don Luscombe Aviation History Foundation (referred to as Luscombe from hereon) Model 8 series airplanes. The proposed action would require installing new inspection holes, modifying the wing tip fairings, and inspecting the wing spars for intergranular corrosion. Reports of intergranular corrosion occurring in the wings prompted the proposed action. The actions specified by the proposed AD are intended to prevent wing spar failure resulting from intergranular corrosion, which, if not detected and corrected, could result in structural failure of the wings and loss of control of the airplane.
