AD/HU 269/35 Amdt 1 Main Rotor Drive Shaft Inspection for Corrosion 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/HU 269/35 Amdt 1.

Schweizer (Hughes) 269 Series Helicopters

AD/HU 269/35 Amdt 1 Main Rotor Drive Shaft - Inspection
for Corrosion 5/2009

Requirement:

CANCELLED.

This AD is cancelled on 7 May 2009.

Background:

This unique Australian AD was originally raised in 1970 against Hughes Service Information Notice (SIN) No. N-69 (now cancelled) requiring an inspection to detect corrosion in the main rotor drive shaft.  This requirement is contained in Schweizer 269 Handbook of Maintenance Instructions (HMI) Section 10-8.

Compliance was: Within 150 hours TIS after 30 June 1970 or at the next scheduled inspection or retirement of the main rotor thrust bearing, (AD DCA/HU 269/28 refer; subject of FAA AD 97-05-06), whichever occurs first.

The contents of this AD have been superseded by manufacturer’s actions that must be complied with as required by Civil Aviation Regulation 1988, 42V; therefore this AD is considered to be no longer required.
