AD/B737/329 - Airworthiness Limitations and Inspections - Fuel Systems - CANCELLED

What this is: This document officially cancels a previous aviation safety rule (Airworthiness Directive 329) that applied to Boeing 737 aircraft.

What it does: It withdraws Australian requirements for inspecting and maintaining fuel systems on Boeing 737 planes. As of 27 January 2010, airlines and operators no longer had to follow this specific Australian directive.

Why it matters: The cancellation happened because the Australian rules were replaced by an updated American Federal Aviation Administration (FAA) directive (AD 2009-10-10R1). Instead of following this cancelled Australian rule, operators must now comply with the newer FAA safety standard referenced in the document.

Who issued it: Mike Higgins, acting as a delegate of the Civil Aviation Safety Authority (CASA), issued this cancellation on 13 January 2010.
