Synopsis
C525 flight crew reported a loud bang with associated roll and yaw. The flight crew performed an in flight shut down of the affected engine; followed by a precautionary landing at the departure airport.
Narrative
Air turn back due to maintenance. Following an uneventful taxi-out; takeoff and climb through FL217; a moderately loud bang was heard with simultaneous right roll and yaw. Engine parameters were immediately checked and found to be normal. A moderately loud rumbling was noted and seemed to be emanating from the nose area. The aircraft remained on autopilot during the event.Climb was continued to FL320 but the Pilot Flying noted that only a slow rate of 750 FPM - 1200 FPM was obtainable. Following some troubleshooting including slowing to 190 kts. and cycling the gear; the crew noted that the right engine Oil Pressure" was no longer being sensed (amber dashed lines) and that the oil temperature in the right engine was indicating substantially lower than the left engine. ZZZ Maintenance Control and Dispatch were contacted and the decision made to return.Following the turn back; further discussion between the crew led to the decision to perform a precautionary shutdown of the right engine as per the Emergency/Abnormal Procedures checklist. As a further precautionary measure; priority handling was requested with ATC. ATC provided normal vectors to a visual approach. At no time during this event did any system fail nor were any CAS messages present. Following an uneventful approach and landing the aircraft was taxied to the parking ramp where it was found that the right engine cowling had partially detached from its mounting attachments."
Second reporter narrative
Air turn back due to maintenance issue. Following an uneventful taxi-out; takeoff and climb through FL215 a moderately loud bang was heard with simultaneous right roll and yaw. Engine parameters were immediately checked and found to be normal. A moderately loud rumbling was noted and seemed to be emanating from the nose area. The aircraft remained on autopilot during the event. Climb was continued to FL320 but the Pilot Flying noted that only a slow rate of 750 FPM - 1200 FPM was obtainable. Following some troubleshooting including slowing to 190 kts. and cycling the gear; the crew noted that the right engine Oil Pressure was no longer being sensed (amber dashed lines) and that the oil temperature was substantially lower than the left. ZZZ Maintenance and Dispatch were contacted and the decision made to return to ZZZ. Following the turn-back; further discussion between the crew led to the decision to perform a precautionary shutdown of the right engine as per the Abnormal Procedures checklist. ATC was informed of the situation and provided vectors to a visual approach Runway XXR at ZZZ. Following an uneventful approach and landing the aircraft was taxied to the parking ramp where it was found that the right engine cowling had partially detached from its mounting attachments.
