AD/AC/57 Pre-Certification Requirements - Modifications 8/2008

Requirement:

CANCELLED.

This AD is cancelled on 31 July 2008.

Background:

This unique Australian AD, issued in 1975, required installation of fuelling equipment bonding points at each fuel filling point, and identification of external earthing points for attachment of ground connections on each main undercarriage assembly, or nose gear.

Compliance was before 31 March 1975.

As these requirements were in accordance with cancelled ANO 101.22, the requirements of this directive are no longer appropriate.

Delegate of the Civil Aviation Safety Authority
