AD/BEECH 90/3 Amdt 1 Tail Unit Inspection 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 90/3 Amdt 1.

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

AD/BEECH 90/3 Amdt 1 Tail Unit - Inspection 7/2008

Requirement:

CANCELLED.

This AD is cancelled on 3 July 2008.

Background:

This unique Australian AD raised in 1972 against Beechcraft Service Instruction (SI) No. 0086-131, required regular scheduled maintenance inspections to be carried out on the elevator and horizontal stabiliser skins, and rudder and elevator torque tube collars.  The manufacturer considered the inspections necessary after cracks had been found on early model King Airs.  Compliance was at intervals not exceeding 50 hours TIS.

As the requirements of this AD have been promulgated for an extended period, no reports have been entered into the SDR reporting system and the manufacturer’s maintenance manual and Schedule 5 adequately address the regular maintenance referred to, this AD is no longer required.
