AD/BEECH 55/7 Grounding Outside Air Temperature Indicator 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 55/7.

Beechcraft 55, 58 and 95-55 (Baron) Series Aeroplanes

AD/BEECH 55/7 Grounding Outside Air
Temperature Indicator 6/2008

Requirement:

CANCELLED.

This AD is cancelled on 5 June 2008.

Background:

This unique Australian AD issued in 1967 against Beechcraft Service Bulletin (SB) No. 66-26, rather than a State of Design AD, required grounding the AOT indicator with metallic tape to eliminate the possibility of static electricity accumulation causing a spark discharge to the magnetic compass.

Compliance was before 1 September 1971.

As all affected aircraft would have complied with this AD by now, it is considered that an unsafe condition no longer exists.

Delegate of the Civil Aviation Safety Authority
