AD/BEECH 90/2 Firewall Fuel Shut-Off Valve Switches 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/BEECH 90/2.

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

AD/BEECH 90/2 Firewall Fuel Shut-Off
Valve Switches - Modification 7/2008

Requirement:

CANCELLED.

This AD is cancelled on 3 July 2008.

Background:

This unique Australian AD, raised in 1967 against Beechcraft Service Bulletin (SB) No. 66-21, Rev.1, required replacement of the firewall fuel shut-off valve switches and installation of identification guards to assist the pilot in distinguishing the firewall fuel shut-off valve switches from the boost pump switches to prevent inadvertent fuel shut-off.

Compliance was forthwith.

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

Delegate of the Civil Aviation Safety Authority
