Plain English Summary

1/10 complexity

This document officially cancels a previous aviation safety rule.

What it does

Revokes Airworthiness Directive AD/CF6/54—a mandatory safety instruction that required specific maintenance actions on high-pressure turbine discs (critical spinning parts inside jet engines) for General Electric CF6 engines.
Switches to a new rule: The old requirements are replaced by a newer directive, AD/CF6/62, which covers the same safety issues.

Who it affects Airlines, maintenance companies, and aircraft owners operating planes with General Electric CF6 engines (commonly found on Boeing 747, 767, and Airbus A300/A330 aircraft).

Why it matters From 26 October 2006, operators no longer need to follow the technical requirements of the old directive (AD/CF6/54). However, they must comply with the replacement directive (AD/CF6/62) instead. This is essentially administrative housekeeping—removing an outdated safety instruction that has been superseded by a more comprehensive one.
