AD/PA-34/23 - Induction, Air Box, Filter Locator Clips - Replacement - CANCELLED

What this is: A cancellation notice for an aviation safety rule known as an Airworthiness Directive (AD).

Who it affects: Owners and operators of Piper PA-34 Seneca series aircraft.

What it does: This document formally scraps a previous requirement (dating back to 1977) that mandated replacement of specific engine parts—induction, air box, and filter locator clips—within 100 hours of flight time.

Why it matters: As of 23 October 2008, these aircraft no longer need to comply with this specific maintenance rule. The replacement requirement has been removed entirely, saving owners time and money, though all other standard aviation safety regulations still apply.
