AD/AC/13 Hydraulic and Engine Oil S/O Valve Circuit Breaker Insulation 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/13.

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

AD/AC/13 Hydraulic and Engine Oil S/O Valve
Circuit Breaker - Insulation 8/2008

Requirement:

CANCELLED.

This AD is cancelled on 31 July 2008.

Background:

This unique Australian AD, issued prior to 1965 against Aero Design (also known as Aero Commander)  Service Bulletin (SB) No. 58, required a modification to ensure the insulation of the hydraulic and engine oil shutoff valve circuit breaker.

Compliance was forthwith.

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