At press time, the service bulletin that grounded a chunk of new Cirrus SR22s progressed to an expected FAA AD (2023-04-08). Continental already has a means for compliance, with tech data in Continental’s Mandatory Service Bulletin MSB23-01.
Cirrus voluntarily grounded some of its Continental-equipped low-time SR models even before the engine maker announced that the crankshaft problem affects roughly 2000 crankshaft assemblies. The service bulletin/AD addresses the crankshafts in new engines and crankshaft assemblies sold as replacement parts. This was on engines and cranks manufactured between June 21, 2021, and Feb. 7, 2023.
