Airworthiness Directive · Amendment 39-18523 · Flight controls
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 accomplishment of a taxi-out checklist which revealed that the elevator movement was partially obstructed due to rotation of the flight control lock adjuster bracket. This AD requires a one-time inspection of the elevator tension control regulator for discrepancies, and corrective actions if necessary. We are issuing this AD to detect and correct discrepancies of the elevator tension control regulators. Such a condition could result in jamming of the elevator mechanism and consequent reduced controllability of the airplane.
At the next scheduled opening of access panels 346AB or 346BL after the effective date of this AD, but no later than 5,000 flight hours after the effective date of this AD: Do a one-time detailed inspection of the elevator tension control regulator for discrepancies, in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-27-095, dated April 22, 2015. If the flight control lock adjuster bracket is found loose, any bracket attachment bolt is found broken, or any nut is missing, before further flight, do all applicable corrective actions in accordance with the Accomplishment Instructions of Fokker Service Bulletin SBF100-27-095, dated April 22, 2015.
Submit a report of any positive findings during any inspection required by paragraph (g) of this AD to Fokker Services B.V., Technical Services Dept., P.O. Box 1357, 2130 EL Hoofddorp, the Netherlands; telephone: +31 (0)88-6280-350; fax: +31 (0)88-6280-111; email: technicalservices@fokker.com; Internet http://www.myfokkerfleet.com.
