Airworthiness Directive · Amendment 39-11461 · Fokker Model F27 Mark 050 Series Airplanes
Fokker Model F27 Mark 050 Series Airplanes
The Federal Register printed this AD without its applicability text. Read it at the link below.
This amendment adopts a new airworthiness directive (AD), applicable to certain Fokker Model F27 Mark 050 series airplanes. This action requires a one-time inspection to verify the tension values of the aileron control cables of the left-and right-hand wings, and corrective actions, if necessary. This action also requires either replacement of the aileron control cables with new, improved aileron control cables, or replacement of the aileron control cables with new, improved aileron control cables and modification of the pulley bracket on the rear face of the bulkhead at frame station 3100. The FAA is issuing this AD in response to mandatory continuing airworthiness information issued by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent interference between the turnbuckles of the aileron control cables and the lightening holes, which could result in binding of the aileron control cables and consequent reduced controllability of the airplane.
