Plain English Summary

1/10 complexity

What this does: This document officially cancels a previous safety rule (Airworthiness Directive AD/PA-31/15) that required owners of Piper PA-31 series aircraft to install a fuse in the alternator field circuit.

Who it affects: Owners and operators of these specific Piper aircraft, though the practical effect is to remove a compliance obligation rather than add one.

Why it matters: The original rule required the fuse installation to prevent electrical system failures. Because all affected aircraft have now been modified as required, the Civil Aviation Safety Authority (CASA) is cancelling the directive to remove unnecessary regulatory burden. As of 31 July 2008, compliance with this specific fuse installation requirement is no longer mandatory.
