AD 94-26876

Abstract

This document proposes to supersede Airworthiness Directive (AD) 83-18-03, which currently requires repetitively inspecting the tailplane outboard hinge assembly for cracks on certain de Havilland DHC-6 series airplanes, and replacing any cracked part. The Federal Aviation Administration's policy on aging commuter-class aircraft is to eliminate, or in certain instances, reduce the number of certain repetitive short-interval inspections when improved parts or modifications are available. The proposed action would require eventually modifying the tailplane outboard hinge arm and tailplane hinge plate as terminating action for the currently required repetitive inspections. The actions specified in the proposed AD are intended to prevent tailplane failure caused by cracks in either the outboard hinge arm or the hinge plate.
