Airworthiness Directive · Amendment 39-18187 · Standard practices/structures
Fokker Services B.V. Airplanes
This AD applies to Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes, certificated in any category, all serial numbers.
We are adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F.28 Mark 0070 and 0100 airplanes. This 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 AD requires installing drain tubes on the center wing rear spar. We are issuing this AD to prevent accumulated water near or on the aileron control cables, which could freeze and result in reduced control of the airplane.
Within 36 months after the effective date of this AD, install water drain tubes on the center wing rear spar, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-51-021, dated April 23, 2013, including the attachments identified in paragraphs (g)(1) through (g)(5) of this AD.
