AD/BEECH 60/7 Alternate Air Ducts 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 60/7.

Beechcraft 60 (Duke) Series Aeroplanes

AD/BEECH 60/7 Alternate Air Ducts 6/2008

Requirement:

CANCELLED.

This AD is cancelled on 5 June 2008.

Background:

This unique Australian AD was raised in 1970 against Beechcraft Service Instruction (SI) 0327-258, rather than a State of Design AD, requiring replacement of the engine induction system fibreglass alternate air ducts with more fire resistant metal ducts.

Compliance was within 100 hours TIS after 31 August 1970.

Given the extended period this AD has been promulgated, and that a State of Design AD has not been published, it is considered that continued publication of this AD to be no longer necessary.  This AD is therefore cancelled.

Delegate of the Civil Aviation Safety Authority
