Accident Overview
While in cruise flight at night, the pilot declared an emergency and reported heavy smoke in the cockpit and an engine fire. Approximately three minutes later, while being vectored by air traffic control to a local airport, the airplane crashed in a residential area.
Witness Observations
Several witnesses, including an air traffic controller, observed a red glow or flames around the front of the airplane prior to impact. The controller stated that when he first saw the airplane, it was headed toward the airport in a descent with its landing lights on. After momentarily turning his attention away, he looked back and noted that the engine area was engulfed in yellow flames. The airplane then began an uncontrolled descent and disappeared from view.
Wreckage Examination
A post-accident examination revealed that the airplane was heavily fragmented from the impact and post-crash fire. Additionally, magnesium engine parts were exposed to water during firefighting efforts, causing further damage to portions of the engine and accessories. Examination of the wreckage showed the majority of in-flight fire damage was located on the right side of the airplane, from the engine cowling back to the right passenger door. The source of the engine fire could not be determined.
