Airworthiness Directives; Fokker Model F28 Mark 1000, 2000, 3000, and 4000 Series Airplanes

요약

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Fokker Model F28 Mark 1000, 2000, 3000, and 4000 series airplanes. This proposal would require replacement of certain hinges on the forward, center, and aft cargo doors with improved hinges. 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 failure of the cargo door hinges caused by stress corrosion or fatigue cracks, which could result in decompression of the airplane, and possible in-flight separation of the cargo door.
