Key Takeaways:

Continental Aerospace Technologies issued an urgent recommendation for the immediate grounding and inspection of certain recently manufactured piston engines (360, 470, 520, and 550 series) due to a crankshaft counterweight retaining ring issue.
The recommendation calls for an inspection within 5 hours for new or rebuilt engines with less than 200 hours in operation.
Cirrus Aircraft proactively grounded its own fleet of SR22s and SR22Ts manufactured between June 1, 2021, and February 7, 2023, as a precautionary measure.
Both Continental and Cirrus Aircraft are expected to release official service bulletins and advisories soon, detailing the scope of the issue, affected aircraft, 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.
