Notice of proposed rulemaking (NPRM).
Summary
We propose to adopt a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This proposed AD was prompted by reports that cracks can occur in a frame of the tail section on certain airplanes. This proposed AD would require a one-time detailed inspection of the oblique frame 67-2 for any cracking, and repair if necessary. We are proposing this AD to detect and correct such cracking, which could lead to failure of the oblique frame 67-2, and consequent loss of the structural integrity of the tail section.
