What happened
The aircraft was being operated for the purpose of a pre-purchase inspection. During the flight, the right engine shut off and could not be restarted.
As the two pilots attempted a single-engine landing, the wind conditions shifted from a quartering headwind to a quartering tailwind. This shift caused the nose and the right wing to drop, resulting in the airspeed decreasing to VMC (minimum controllable airspeed).
In response to the loss of control, the crew initiated a single-engine go-around. However, contrary to the procedures outlined in the flight manual, the pilots did not retract the flaps and landing gear during this maneuver. Consequently, the aircraft was unable to climb over a tree located at the end of the runway departure area. The airplane struck the tree, rolled into the dead engine, and ultimately crashed into trees in a vertical, nose-down attitude.
The investigation
Following the accident, the right engine was examined and subsequently operated on a test stand.
