Airworthiness Directive · Amendment 39-12367 · Fokker Model F27 Mark 050 Series Airplanes
Fokker Model F27 Mark 050 Series Airplanes
Model F27 Mark 050 series airplanes, as listed in Fokker Service Bulletin SBF50-53-054, dated May 1, 2000, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F27 Mark 050 series airplanes. This action requires installation of a filler plate and a doubler to reinforce the area under the top antenna for the Traffic Collision Avoidance System (TCAS). This action is necessary to prevent cracking due to fatigue in the area under the antenna for the TCAS, which could result in reduced structural capability of the airplane. This action is intended to address the identified unsafe condition.
