Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD), for certain Fokker Services B.V. Model F28 Mark 0100 airplanes. This proposed AD was prompted by an analysis which determined that, for certain areas of the fuselage, the current threshold of an Airworthiness Limitations Section inspection is insufficient to detect early crack development. This proposed AD would require one time high and low frequency eddy current inspections of the affected fuselage skin for cracks and repair if necessary. We are proposing this AD to detect and correct cracks in the fuselage skin; such cracking could result in reduced structural integrity of the fuselage.
