Plain English Summary

2/10 complexity

What this is: A mandatory safety directive (called an Airworthiness Directive) issued by the Civil Aviation Safety Authority requiring a specific inspection on certain Cessna aircraft.

Who it affects: Owners and operators of Cessna 340 and 340A aeroplanes with serial numbers listed in Cessna Service Information Letter (SIL) ME81-35.

What it requires: Operators must inspect the elevator balance weights (counterweights attached to the tail control surfaces that help stabilize the aircraft) to verify they are correctly attached and not loose. The inspection must follow the procedures outlined in Cessna SIL ME81-35.

Why it matters: The manufacturer discovered that aircraft fitted with improved stabilisers and elevators might have balance weights that were installed incorrectly or have worked loose. If these weights detach during flight, they could cause serious control problems or structural damage.

Compliance deadline: The inspection must be completed within 100 hours of flight time after 31 March 1982.
