AD/BEECH 90/35 Flap Gearbox Inspection of Gears Cancelled (Cth)

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 90/35.

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

AD/BEECH 90/35 Flap Gearbox - Inspection of Gears 7/2008

Requirement:

CANCELLED.

This AD is cancelled on 3 July 2008.

Background:

This unique Australian AD was raised in 1975 against Beechcraft Service Instruction (SI) 0689-160 requiring a one time inspection, and necessary rework, of the outboard flap drive gear in the flap gearbox assembly for proper material and/or possible excessive wear that could cause the outboard flaps to be inoperative.

Compliance was within 100 hours TIS after 31 January 1975.

As all affected aircraft would have been inspected and modified by now, it is considered that the AD is no longer required.
