Airworthiness Directives; Fokker Services B.V. Airplanes

摘要

We propose to adopt a new airworthiness directive (AD) for certain Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This proposed AD was prompted by three reports of cracking in the rear pressure bulkhead (RPBH) web. This proposed AD would require inspecting the RPBH web for cracking, and repairing if necessary. We are proposing this AD to detect and correct cracking of the RPBH web, which could result in in-flight decompression of the airplane and possible injury to the occupants.
