Owners had to comply with Piper Service Bulletin No. 467 before flying after December 1975.\n\n**What this does now:** Completely cancels that modification requirement. The safety concern is no longer considered a risk, so owners and operators no longer need to comply with the previous directive.\n\n**Who it affects:** Owners and operators of affected Piper PA-36 agricultural aircraft, though given the original 1975 compliance deadline, this primarily clears historical compliance obligations."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pa-36-10-spray-pump-windmill-modification-cancelled","history":"/api/acts/ad-pa-36-10-spray-pump-windmill-modification-cancelled/history","analysis":"/api/acts/ad-pa-36-10-spray-pump-windmill-modification-cancelled/analysis","conflicts":"/api/acts/ad-pa-36-10-spray-pump-windmill-modification-cancelled/conflicts","importantCases":"/api/acts/ad-pa-36-10-spray-pump-windmill-modification-cancelled/important-cases","documents":"/api/acts/ad-pa-36-10-spray-pump-windmill-modification-cancelled/documents"}}
