Electrical Equipment

AD/ELECT/45 Aircraft Batteries - Exide
Type 6AC9 and 6AC11 2/2009

Requirement:

CANCELLED.

This AD is cancelled on 12 February 2009.

Background:

This unique Australian AD raised in 1984 required an inspection and replacement of Exide type 6AC9 and 6AC11 batteries with S/nos 32659 to 33117 following the manufacturer issuing a recall notice due problems being experienced with epoxy resin used to seal them.

Compliance was: 1. Inspect for leakage upon receipt of AD and thereafter at each Daily inspection until battery replaced; and 2. Replace battery upon detecting a cracked battery or within 50 hours TIS after 30 June 1984 if battery found serviceable after compliance with Para. 1.

As all affected batteries would have been replaced by now, this AD is considered to be no longer required.
