Airworthiness Directives; Israel Aircraft Industries, Ltd., Model Astra SPX Series Airplanes

概要

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Israel Aircraft Industries Model Astra SPX series airplanes. This proposal would require a one- time inspection to measure the countersink angle of the bolt holes in the lower scissors fitting of the horizontal stabilizer, and corrective actions, if necessary. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent cracks in the lower scissors fitting and fitting attachment bolts of the horizontal stabilizer, which could result in possible in-flight loss of the horizontal stabilizer and consequent reduced controllability of the airplane.
