Airworthiness Directives; Beech Aircraft Corporation Models 34C, T-34C, and T-34C-1 Airplanes

Краткое содержание

This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Beech Aircraft Corporation (Beech) Models 34C, T-34C, and T-34C-1 airplanes. The proposed action would require replacing the eight wing attachment steel bolts and hardware with Inconel bolts and hardware. A report of the right lower aft wing attachment nut assembly separating in two pieces on a Model T-34C-1 airplane prompted the proposed action. The actions specified by the proposed AD are intended to prevent the wing from separating from the fuselage because of failure of this assembly.
