At about 1745 Eastern time, the airplane was substantially damaged when it impacted terrain while on approach. The Private pilot and passenger were fatally injured. Visual conditions prevailed for the flight from McMinnville, Tenn. At 1738, the airplane was about 10 miles northwest of Annapolis, Md., its destination, at 2500 feet. The pilot was instructed by ATC to continue the flight on its current transponder code, and approved to change to the local airport advisory frequency. There were no known further communications from the airplane. A witness living near the airport reported hearing a sound similar to “wind blowing through trees,” which was followed by an increasing engine noise, which became very loud, “like the engine was revved up to full power.” He then heard a loud impact.
