AD/B747/378 - Airworthiness Limitations and Inspections - Fuel Systems - CANCELLED

This instrument cancels Australian Airworthiness Directive 378 for Boeing 747 fuel‑system inspections and substitutes compliance with the US FAA directive AD 2008‑10‑06 R1 (Dec 2009). It affects Australian Boeing 747 owners, operators and maintenance organisations, who must follow the referenced FAA rule instead of the old Australian requirements. The change reflects automatic recognition of certain US airworthiness directives to avoid duplicate regulation, effective 22 January 2010.
