Key Takeaways:

Continental Aerospace Technologies has recommended the immediate grounding of certain piston engines, particularly those powering Cirrus SR22 series aircraft, due to a potential issue.
The recommendation now covers a broader range of Continental engine models (360, 470, 520, 550 series) and mandates a specific crankshaft counterweight retaining ring inspection within 5 hours for new or rebuilt engines with under 200 hours.
Cirrus Aircraft has proactively grounded its own SR22s and SR22Ts manufactured between June 1, 2021, and February 7, 2023, as a precautionary measure, pending official service bulletins detailing the root cause and corrective actions.

An urgent notification to customers and operators of Cirrus SR22 series airplanes powered by certain piston engines manufactured recently by Continental Aerospace Technologies suggests an immediate grounding would be prudent.

On Friday, Continental Aerospace sent out its own updated recommendation, shared with FLYING, broadening the scope of the recommended grounding to encompass a wide range of powerplants and to call for a specific inspection of the crankshaft counterweight retaining ring within 5 hours for those new or rebuilt engines with less than 200 hours in operation since installation. Models include those in the 360, 470, 520, and 550 series.
