A Cessna 560 Encore corporate jet, N810QS, was substantially damaged when an engine cowling departed the airplane inflight. The two flight crewmembers and one passenger on-board were not injured. Visual meteorological conditions prevailed for the flight, which operated on an instrument flight rules flight plan. The flight originated from Fort Myers-Southwest Florida Regional Airport, FL (RSW), at approximately 13:30 EST.
The airplane was on initial descent, passing 17,000 feet mean sea level when the flight crew reported hearing a "bang" and experienced a slight yawing of the airplane. They believed it was a gear door departing the airplane and reported the event to air traffic control. There were no indications received in the flight deck. The flight crew disconnected the auto-pilot and the airplane "flew normally." The flight continued to Chicago-Midway Airport, IL (MDW) where the airplane landed without incident. A post flight inspection revealed the right engine cowling had departed the airplane and impacted the right horizontal stabilizer.

Probable Cause:

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