AD/LA-4/5 Battery Relay 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/LA-4/5.

Consolidated Aeronautics, Colonial and LA-4 Series Aeroplanes

AD/LA-4/5 Battery Relay - Installation 7/2009

Requirement:

CANCELLED.

This AD is cancelled on 2 July 2009.

Background:

This unique Australian AD was raised in 1972 requiring a modification by installation of a battery relay adjacent  to the battery so that battery power can be disconnected in-flight from the heavy duty cables at a point as close to the battery as possible.  Compliance was before issue of a certificate of airworthiness, or within 200 hours TIS after 31 May 1972.

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.
