Confidence Rating: Accident investigation report completed and information captured
During a post-flight inspection at Charleston Executive Airport, South Carolina, USA, it was discovered that the no.1 (left) engine cowling had separated, damaging the fuselage, left horizontal stabilizer and left elevator trim.

The airplane was descending through about 21,000 ft about 15 minutes from Charleston Executive Airport, SC, when the flight crew heard and felt a loud bang, shudder, and yaw. The autopilot was disconnected, and a noticeable yaw was felt; however, there were no anomalies noted on any flight or engine instruments. The flight crew continued and landed without further incident. During the post-flight inspection, it was discovered that the left engine cowling had entirely separated.

Probable cause: The in-flight separation of the left engine’s four-panel cowling for reasons that could not be determined based on the available evidence.
