AD/AS 355/32 - Servo Control Securing Screws - CANCELLED

What this is: This document officially cancels a previous aviation safety rule affecting Eurocopter AS 355 (Twin Ecureuil) helicopters.

What it did: The cancelled rule required inspection and tightening of screws in the servo control system (the mechanism that helps control the helicopter) within 25 hours of flight time. This was a unique Australian requirement first imposed in 1988, not based on the manufacturer's own guidelines.

What changed: The inspection requirement is no longer mandatory. The Civil Aviation Safety Authority (CASA) has determined this specific safety check is unnecessary and has revoked it.

Who it affects: Owners and operators of Eurocopter AS 355 helicopter series.

Why it matters: If you operate one of these helicopters, you no longer need to perform this particular screw inspection that was previously required only under Australian regulations.
