This Directive was not based on a US Directive.

The original rule required aircraft owners to replace a specific fuel valve within 100 hours of flying time after March 1975. Because that deadline passed decades ago, the Civil Aviation Safety Authority cancelled the directive on 3 July 2008. **What this means:** The fuel valve replacement requirement is no longer in force, though any work already completed remains valid."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-28-55-fuel-valve-replacement-cancelled","history":"/api/acts/ad-pa-28-55-fuel-valve-replacement-cancelled/history","analysis":"/api/acts/ad-pa-28-55-fuel-valve-replacement-cancelled/analysis","conflicts":"/api/acts/ad-pa-28-55-fuel-valve-replacement-cancelled/conflicts","importantCases":"/api/acts/ad-pa-28-55-fuel-valve-replacement-cancelled/important-cases","documents":"/api/acts/ad-pa-28-55-fuel-valve-replacement-cancelled/documents"}}
