Airworthiness Directive · Amendment 39-9752 · Various Airplanes
Various Airplanes
This AD applies to Various F.28 Mark 1000, F.28 Mark 2000, F.28 Mark 3000, F.28 Mark 4000.
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) that is applicable to certain Fokker Model F28 Mark 1000, 2000, 3000, and 4000 series airplanes. This action requires a one-time inspection to detect cracks of the dimpled lap joints in the fuselage skin, and repair of cracked lap joints. This amendment is prompted by a report indicating that cracks were found at various locations in the outer skin of the dimpled longitudinal lap joints of the fuselage skin. The actions specified in this AD are intended to prevent such cracking, which could result in reduced structural integrity of the fuselage and/or rapid decompression of the airplane.
