Plain English Summary

1/10 complexity

This instrument is a housekeeping measure by the Civil Aviation Safety Authority (CASA) that cancels 11 outdated safety directives for specific aircraft types.

What it does:
It formally revokes (cancels) old Airworthiness Directives (ADs) — which are mandatory safety rules requiring specific maintenance or modifications — for certain Boeing 747, Airbus A320, and helicopter engine models.

Who it affects:
Airlines and aircraft operators who maintain these specific aircraft models, including those with:

Bell helicopter engines (CT58 series) — 8 directives revoked
Boeing 747 (AD/B747/132)
Airbus A320 (AD/A320/184)
Turbomeca Arriel engines (AD/ARRIEL/35)

Why it matters:
It removes obsolete regulatory burdens. Once revoked, operators no longer need to comply with these specific maintenance requirements, typically because newer safety measures have replaced them or the original safety issue has been resolved through fleet modifications. The revocations take effect on various dates between 28 October and 12 November 2010.
