What happened
A private pilot was attempting to take off from a private airstrip characterized by rough grass surfaces. During the initial phase of the takeoff roll, the airplane encountered an uneven section of the runway surface. This irregularity caused the aircraft to veer sharply to the left, deviating from the intended flight path.
As the aircraft continued its uncontrolled movement, the nose landing gear struck a large hole that was obscured by grass cover. The impact with this depression caused the airplane to rotate rapidly about its vertical axis. During this rotation, the left wing of the aircraft made contact with a nearby tree. The collision with the tree and the ground initiated a fire, which ultimately led to the total destruction of the aircraft.
The investigation
The investigation focused on the sequence of events leading to the loss of control during the takeoff phase. Investigators examined the condition of the airstrip and the immediate aftermath of the accident. The rough nature of the grass surface and the presence of the hidden hole were identified as critical environmental factors contributing to the incident.
Findings
The primary factor in this accident was the pilot's inability to maintain directional control due to the uneven takeoff surface. The combination of a rough grass airstrip and a concealed hazard, specifically the large grass-covered hole, played a significant role in the loss of control. The impact with the tree and the subsequent fire were direct consequences of the aircraft veering off the runway.
Safety message
Pilots operating from private or unimproved airstrips should exercise extreme caution regarding surface conditions. Uneven terrain and hidden obstacles can significantly affect aircraft handling during critical phases of flight, such as takeoff. Awareness of the specific hazards present at the departure location is essential for maintaining control.
