AD/BEECH 95/20 Hatshelf Soundproofing Blanket 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 95/20.

Beechcraft 95 (Travelair) Series Aeroplanes

AD/BEECH 95/20 Hatshelf Soundproofing Blanket 8/2008

Requirement:

CANCELLED.

This AD is cancelled on 31 July 2008.

Background:

This unique Australian AD, raised in 1979 against Beechcraft Service Instruction (SI) 0694-311, Revision 1, required an inspection and/or repair to ensure a good bond existed between the cabin soundproofing blanket and the bottom of the hat shelf to prevent the possibility of the blanket coming into contact with primary control cables.  Compliance was at intervals not exceeding 100 hours TIS.

Although this AD is repetitive (imposed by the manufacturer) there are no reports of defects in the defect reporting system.  This requirement should be covered by normal maintenance practices which require inspection of control cable runs, and as all affected aircraft would have been inspected and repaired by now, this AD is no longer required.
