Airworthiness Directives; Fokker Services B.V. Airplanes

We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and Mark 0100 airplanes. This proposed AD was prompted by reports of cracking in a certain area of the pressure bulkhead webplate and skin connection angle. This proposed AD would require a one-time inspection of the affected pressure bulkhead webplate and skin connection angle, and corrective actions if necessary. We are proposing this AD to detect and correct cracking of the pressure bulkhead webplate and skin connection angle that could lead to sudden inflight decompression of the airplane resulting in injury to occupants.
