This had to be done within 100 hours of flying time after June 1979.\n\n**Why it matters:** As of 3 July 2008, this maintenance requirement no longer applies. The authority cancelled the rule because all affected aircraft would have completed the required modifications decades ago, making the mandatory rule unnecessary."}},"importantCases":[],"_links":{"self":"/api/acts/ad-beech-76-2-cowl-flap-hinge-assemblies-cancelled","history":"/api/acts/ad-beech-76-2-cowl-flap-hinge-assemblies-cancelled/history","analysis":"/api/acts/ad-beech-76-2-cowl-flap-hinge-assemblies-cancelled/analysis","conflicts":"/api/acts/ad-beech-76-2-cowl-flap-hinge-assemblies-cancelled/conflicts","importantCases":"/api/acts/ad-beech-76-2-cowl-flap-hinge-assemblies-cancelled/important-cases","documents":"/api/acts/ad-beech-76-2-cowl-flap-hinge-assemblies-cancelled/documents"}}
