What this does

This instrument cancels (revokes) a specific aviation safety order — Airworthiness Directive AD/CFM56/31 — effective 9 March 2012.

What is an Airworthiness Directive?

These are mandatory safety instructions issued by the Civil Aviation Safety Authority (CASA) to fix unsafe conditions in aircraft, engines, or parts. Compliance is legally required.

Who it affects

Aircraft operators, maintenance organisations, and engineers who operate or service aircraft with CFM56 engines (commonly used in Boeing 737 and Airbus A320 family aircraft).

Why it matters

This removes a specific maintenance or inspection requirement. This typically happens when:

The safety issue has been permanently fixed through design changes
The directive has been replaced by a newer requirement
CASA determines the safety risk no longer justifies the compliance burden

Operators no longer need to follow the specific instructions in AD/CFM56/31 from 9 March 2012 onwards.
