Plain English Summary

1/10 complexity

This Airworthiness Directive (AD) is a compulsory safety notice issued by the Civil Aviation Safety Authority (CASA) requiring a mechanical check on specific aircraft.

What it requires: Operators must inspect the rudder bellcranks — the pivot joints that transfer movement from the pilot's foot pedals to the rudder on the tail. The check must be carried out exactly as described in Swearingen Service Bulletin 27-20-3040.

Who is affected: Only owners of Fairchild Swearingen SA226T aircraft with serial numbers T-201 through T-234.

Why it matters: Faulty bellcranks can cause the pilot to lose directional control. The directive imposes a strict deadline: the inspection must be done within 10 hours of flight time after 27 August 1973.

In short: If you operate one of these specific aircraft, you must complete this inspection immediately to remain airworthy and comply with the law.
