Plain English Summary

1/10 complexity

The Civil Aviation Safety Authority (CASA) has cancelled an old aircraft maintenance rule.

What this does: This instrument formally revokes Airworthiness Directive AD/AL 250/82, which previously set safety requirements for the hydromechanical unit power lever angle potentiometer (a sensor that measures throttle position) on Allison 250 series turbine engines.

Why it matters: The old rule has been replaced by a newer directive (AD/AL 250/84). This cancellation removes the outdated requirement from the rulebook, ensuring aircraft mechanics and operators follow only the current safety standards. If you operate or maintain aircraft with these engines, you must now comply with the replacement directive instead of this cancelled one.
