What happened
On July 24, 2008, a Dyn’Aero S MCR 4S (registration PH-YOO) was performing its initial test flight from Lelystad Airport. Shortly after departing from runway 05, the aircraft experienced a sudden loss of engine power at an altitude of approximately 200 feet. An eyewitness reported hearing unusual noises coming from the engine just before the power loss occurred.
In an attempt to manage the emergency, the pilot initiated a 180-degree left turn, likely intending to reach the nearby Micro Light Aircraft (MLA) runway. During this maneuver, the left wing struck the ground, causing the aircraft to capsize. The aircraft came to rest in a cornfield near the threshold of the MLA runway. The pilot sustained serious injuries, and the aircraft was destroyed.
The investigation
The investigation focused on the sequence of events following the engine malfunction. Investigators examined the flight path and the pilot's actions during the emergency. It was noted that while the pilot attempted a 180-degree turn to reach the MLA runway, the altitude was insufficient to complete the maneuver safely. There was no evidence to suggest that attempting an emergency landing in the direction of the takeoff was not a viable option.
Findings
- The primary cause of the accident was a loss of engine power shortly after takeoff.
- The pilot's attempt to execute a 180-degree turn to reach an alternative runway was unsuccessful due to insufficient altitude.
- The impact occurred when the left wing made contact with the ground during the turn, leading to the aircraft's destruction.
