Plain English Summary

2/10 complexity

What this is: A mandatory safety order (called an Airworthiness Directive) issued by the Civil Aviation Safety Authority (CASA) requiring specific aircraft owners to perform a safety inspection.

What it requires: Owners and operators must inspect the fuel selector valve on affected aircraft according to the technical instructions in Piper Service Bulletin No. 455.

Who it affects: Only applies to Piper PA-23-250 model aircraft with specific serial numbers listed in the document (including ranges like 27-7305127 to 27-7554008 and various individual numbers).

When compliance is required: Within 100 hours of flight time (counted from when the aircraft is airborne) after 31 July 1975.

Why it matters: Faulty fuel selector valves can cause engine failure due to fuel starvation or leakage. This inspection prevents potentially catastrophic in-flight emergencies by ensuring the valve mechanism is functioning correctly.
