Once the cancellation takes effect, aircraft operators no longer need to comply with the specific inspection or maintenance requirements from the old directive.\n\n**Who is affected:**\nOwners and operators of aircraft fitted with the affected McCauley threaded propellers, who are now released from the compliance obligations of the cancelled directive."}},"importantCases":[],"_links":{"self":"/api/acts/ad-pmc-47-amdt-2-mccauley-threaded-propellers-cancelled","history":"/api/acts/ad-pmc-47-amdt-2-mccauley-threaded-propellers-cancelled/history","analysis":"/api/acts/ad-pmc-47-amdt-2-mccauley-threaded-propellers-cancelled/analysis","conflicts":"/api/acts/ad-pmc-47-amdt-2-mccauley-threaded-propellers-cancelled/conflicts","importantCases":"/api/acts/ad-pmc-47-amdt-2-mccauley-threaded-propellers-cancelled/important-cases","documents":"/api/acts/ad-pmc-47-amdt-2-mccauley-threaded-propellers-cancelled/documents"}}
