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.
