AD/AC/8 Power Brake Valve 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/8.

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

AD/AC/8 Power Brake Valve - Modification 9/2008

Requirement:

CANCELLED.

This AD is cancelled on 28 August 2008.

Background:

This unique Australian AD, issued prior to 1961 against Aero Design (also known as Aero Commander) Service Bulletin (SB) No. 48, required a modification, for aircraft with nose wheel steering installed, to prevent the possibility of the landing gear failing to retract during single engine go-around after take-off.

Compliance was forthwith.

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

Delegate of the Civil Aviation Safety Authority
