AD/DO-27/10 Stall Warning System Installation 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/DO-27/10.

Dornier DO-27 Series Aeroplanes

AD/DO-27/10 Stall Warning System - Installation 8/2009

Requirement:

CANCELLED.

This AD is cancelled on 30 July 2009.

Background:

This unique Australian AD raised in 1974 against Dornier modification kit drawing No. 27.837 required a modification by installation of a stall warning system as DO-27 did not exhibit any form of natural stall warning.

Compliance was:  Before 1 October 1983.

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