Plain English Summary

2/10 complexity

This Airworthiness Directive requires operators of Fokker F.28 Mk 100 and Mk 0070 aircraft fitted with certain Elevator Tension Regulator part numbers to modify or replace those regulators following Fokker service instructions. It responds to a reported loose bolt that restricted elevator movement. Compliance was required by 1 December 2003 and the AD took effect on 5 September 2002. Operators bear the cost and maintenance time to perform the manufacturer-prescribed work to restore the regulator design specified in the service bulletins.
