AD/HU 269/79 Amdt 1 Main Rotor Drive Shaft 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 269/79 Amdt 1.

Schweizer (Hughes) 269 Series Helicopters

AD/HU 269/79 Amdt 1 Main Rotor Drive Shaft 5/2009

Requirement:

CANCELLED.

This AD is cancelled on 7 May 2009.

Background:

This unique Australian AD raised in 1987 against Schweizer Service Information Notice (SIN) No. N-199.1 required a one-time hardness test inspection of main rotor drive shaft.

Compliance was: At next 300, 400, 600 or 1200 hour inspection, whichever comes first after 30 June 1986.

This AD has been sufficiently promulgated for the affected aircraft to have been inspected by now; therefore this AD is considered to be no longer required.

Delegate of the Civil Aviation Safety Authority
