AIRWORTHINESS DIRECTIVE

On the effective date specified below, and for the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive AD/BEECH 90/37.

Beechcraft 90 and 65-90 (King Air) Series Aeroplanes

AD/BEECH 90/37 Elevator and Rudder Trim Tab
Actuator Systems - Inspection 7/2008

Requirement:

CANCELLED.

This AD is cancelled on 3 July 2008.

Background:

This unique Australian AD, issued in 1975 against Beechcraft Service Instruction (SI) No. 0691-133, - 135.  For those aircraft which have in excess of 300 hours TIS the SI required a repetitive inspection of the elevator and rudder trim tab actuator rod ends for looseness and excessive wear due to incorrect maintenance and/or inspections.

Compliance was within 25 hours TIS after 22 January 1975 and thereafter at intervals not exceeding 100 hours TIS.

As the manufacturer’s maintenance manuals have been amended, Schedule 5 requirements are adequate, and no defect has been recorded in the mandatory recording system, this AD is no longer required.
