Action
Final rule.
Summary
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.
