What happened
The incident occurred while the aircraft was conducting an agricultural spraying operation under the provisions of 14 CFR Part 137. The pilot, holding a private certificate but not qualified for commercial crop dusting operations, was executing a spraying pass when the engine suddenly lost all power. The cause of this mechanical failure remained undetermined at the time of the report.
Following the loss of thrust, the pilot initiated an emergency descent to attempt a forced landing. During this maneuver, the airplane collided with a tree, which caused the aircraft to go out of control. The失控 aircraft then struck a residential house before impacting the ground. Upon ground impact, the airplane was completely destroyed by post-crash fire.
The investigation
The investigation focused on the sequence of events leading to the loss of power and the subsequent collision with terrain and structures. Investigators noted that the pilot was not qualified for the specific commercial operation being performed under Part 137 regulations. No further mechanical analysis details were provided in the source text regarding the engine failure itself.
Findings
The primary factors contributing to the accident included the total loss of engine power during a critical phase of flight and the pilot's lack of qualification for the commercial agricultural operation. The collision with the tree and house was a direct result of the inability to maintain controlled flight after the power failure.
