AD/PA-42/14 - Tailcone Drain Holes - CANCELLED

This document cancels a previous aircraft safety rule for Piper PA-42 (Cheyenne III) aeroplanes.

What it did previously: The original Airworthiness Directive (AD) required owners to inspect drain holes in the aircraft's tailcone according to Piper Service Bulletin No. 857. This had to be done at the next maintenance check or within 50 flight hours after June 1987.

What this document does: It removes that inspection requirement effective 9 April 2009.

Who is affected: Owners and operators of Piper PA-42 (Cheyenne III) series aircraft.

Why it matters: This cancels a specific maintenance obligation, meaning operators no longer need to schedule or pay for these mandated tailcone drain hole inspections. The Civil Aviation Safety Authority determined the safety requirement was no longer necessary.
