This is a serious structural integrity issue; if the collars are missing, the wing attachment could be compromised.\n\n**What operators must do:**\nFollow the inspection and repair instructions in **Piper Service Bulletin No. 820** within **10 hours of flight time** after 9 April 1986.\n\n**Why it matters:**\nThis prevents potential wing structural failure by ensuring the fasteners securing the wings to the body of the aircraft are properly retained."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-46-10-aft-wing-attach-fitting-fastener-collars","history":"/api/acts/ad-pa-46-10-aft-wing-attach-fitting-fastener-collars/history","analysis":"/api/acts/ad-pa-46-10-aft-wing-attach-fitting-fastener-collars/analysis","conflicts":"/api/acts/ad-pa-46-10-aft-wing-attach-fitting-fastener-collars/conflicts","importantCases":"/api/acts/ad-pa-46-10-aft-wing-attach-fitting-fastener-collars/important-cases","documents":"/api/acts/ad-pa-46-10-aft-wing-attach-fitting-fastener-collars/documents"}}
