Airworthiness Directive · Amendment 39-9446 · Various Airplanes
Various Airplanes
Superseded. A later AD replaced this one: AD 2018-01-09. Comply with the one in force.
This AD applies to Various F.28 Mark 0100.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F28 Mark 0100 series airplanes. This action requires inspection(s) to detect cracks of the fuselage-mounted half of hinge assemblies of the small cargo door, and replacement of any cracked hinge assembly with a new hinge assembly. This amendment is prompted by a report that the hinges of the small cargo door on these airplanes are made of a material that is sensitive to stress corrosion cracking. The actions specified in this AD are intended to prevent failure of the hinges of the small cargo door due to stress corrosion cracking, which could result in opening and/or separation of the door while the airplane is in flight, and resultant rapid decompression and/or structural damage to the airplane.
