AD/AC/23 Main Landing Gear Struts Inspection and Modification 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/AC/23.

Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600 and 700) Series Aeroplanes

AD/AC/23 Main Landing Gear Struts - Inspection
and Modification 8/2008

Requirement:

CANCELLED.

This AD is cancelled on 31 July 2008.

Background:

This unique Australian AD, raised in 1962  against Aero Commander Service Bulletin (SB) No. 80, required an inspection and modification of the main landing gear strut needle bearings to ensure rotation during retraction/extension cycle.

Compliance was forthwith.

As all affected aircraft would have been inspected and modified by now, this AD is considered to be no longer required.

Delegate of the Civil Aviation Safety Authority
