AD/PA-28/73 - Hose Assembly - Inspection and Modification - CANCELLED

What this is: A cancellation notice for an old aviation safety rule (Airworthiness Directive AD/PA-28/73) that previously required owners of Piper PA-28 aircraft to inspect and replace certain hose assemblies.

Who it affects: Owners and operators of Piper PA-28 series aeroplanes (light aircraft).

What it does: This document officially cancels the inspection requirement as of 3 July 2008. The original rule required a one-time inspection of hose assemblies following a manufacturer's service bulletin (SB No. 611), with compliance due within 10 hours of flying time after December 1978.

Why it matters: Since all affected aircraft have now completed the required inspection (the deadline was 30 years prior), the rule is obsolete. This cancellation removes an unnecessary regulatory burden while confirming the safety issue has been addressed across the fleet.
