Probable cause

The inflight separation of the upper and lower right engine cowlings for reasons that could not be determined based on available evidence.

NTSB narrative

The flight crew of the twin-engine jet heard a "bang," and experienced a slight yawing of the airplane during the initial descent for landing. The flight continued to a normal landing, and a post-flight inspection revealed that the right engine upper and lower cowlings had separated from the engine and struck the right horizontal stabilizer. Recovered sections of the departed cowling doors were examined, but the reason for the separation could not be determined because the engine cowling quick-release fasteners were not recovered.

Analysis
