Plain English Summary

1/10 complexity

What this is: A mandatory safety instruction (called an Airworthiness Directive) issued by the Civil Aviation Safety Authority for specific Piper aircraft.

Who it affects: Owners and operators of Piper PA-30 and PA-39 (Twin Comanche) aircraft registered after 31 May 1972.

What it requires: You must install an ammeter (a gauge that measures electrical current) on each generator's power line. This gives pilots a way to continuously monitor the electrical system during flight to catch problems before they become dangerous.

Alternative option: Instead of separate ammeters, you can use one switchable ammeter that can alternate between the battery and generator lines, provided the switch can be set to monitor a generator line at all times during flight.

When you must comply: Immediately (the directive uses the term "forthwith").
