Plain English Summary

1/10 complexity

What this is: An Airworthiness Directive — a mandatory safety order issued by the Civil Aviation Safety Authority requiring a specific mechanical fix on certain aircraft.

Who it affects: Owners and operators of Lake LA-4 model aeroplanes with serial numbers 246 and higher.

What you must do: Install a fuel filter on the aircraft exactly as instructed in the manufacturer's document called Consolidated Aeronautics Service Letter No. 36.

When: The installation must be completed within 100 hours of flight time (counted from when the aircraft is actually flying, not just idling on the ground) after 31 May 1972.

Why it matters: This prevents contaminants from reaching the engine, reducing the risk of engine failure and ensuring the aircraft remains legally airworthy and safe to fly.
