Introduction
On an unspecified date, an aircraft experienced a loss of control shortly after taking off from an airstrip with an elevation of 5,650 feet. The incident occurred before the aircraft reached 500 feet above ground level (AGL), resulting in a collision with trees and a subsequent ground impact followed by a severe fire.
Narrative
Witnesses reported that from rotation until the loss of control, the aircraft maintained an extreme nose-high attitude. They observed the left wing drop, which they described as resembling either an intentional left turn or a departure stall. After striking trees, the aircraft impacted the ground and erupted into flames. The post-impact fire was severe, leading to the destruction of the aircraft's systems.
Investigation
An examination of the aircraft's engine and turbocharging system was conducted, including a teardown, but no abnormalities were found. Investigators could not determine a mechanical reason for the nose-high attitude or the loss of control. The aircraft's weight was below the maximum gross weight, and the center of gravity (CG) was within limits. Density altitude at the time was approximately 7,000 feet. This was the second flight of the day for the pilot and passenger.
Conclusion
The investigation did not identify a mechanical cause for the loss of control. The circumstances suggest a possible aerodynamic stall, but no definitive conclusion was reached.
