What happened
During the cruise phase of flight at 16,000 feet, the pilot performed a series of maneuvers, including two 360-degree turns. After requesting radar vectors to the nearest airport, the pilot informed air traffic control of an asymmetric fuel condition. Following this report, the pilot was cleared to descend to 4,000 feet. Approximately one minute later, the pilot broadcasted "Mayday" six times, after which all radio and radar communication with the aircraft ceased.
Radar tracking data indicated the aircraft was traveling south at 16,100 feet MSL at 1803:13. The aircraft's flight path involved several turns, including a left turn to a southeasterly heading and a subsequent right turn back to a southerly heading. By 1809:04, the aircraft was heading west at 15,400 feet. The final radar contact occurred at 1810:06, with the aircraft at 13,800 feet.
The wreckage was discovered north of the final radar position. Eyewitnesses reported seeing the aircraft descend in a nearly vertical orientation, striking the ground and resulting in an explosion. Debris from the engines, propellers, and various flight control surfaces were recovered at the site. Due to the intensity of the post-crash fire and the impact, investigators were unable to examine the aircraft's fuel system.
Findings
- The pilot reported an asymmetric fuel condition prior to the loss of contact.
- The aircraft's final descent was observed by witnesses to be in a near vertical attitude.
