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 a report of two cases of heavy (hard to move) aileron control caused by aileron cables stuck in a clump of ice in the wheel bay. This proposed AD would require installing drain tubes on the center wing rear spar. We are proposing this AD to prevent accumulated water near or on the aileron control cables, which could freeze and result in reduced control of the airplane.
