Accident Narrative
The pilot reported that the western one-third of Runway 9 consisted of rough chat rock and packed soil, while the remaining runway surface was asphalt. The pilot elected to perform a no-flap takeoff, using the full length of the runway.
Due to the rough runway surface, the pilot applied up elevator control pressure to relieve loads on the nose gear and to raise the propellers slightly off the gravel surface. The intention was to progressively relieve the up elevator control and achieve takeoff at 86 knots.
Shortly after the aircraft began its takeoff roll, it reportedly entered a nose-high attitude and became airborne prematurely. The aircraft then yawed to the left and subsequently collided with trees located near the north edge of the runway.
Pilot Injuries
The pilot, who was seriously injured, stated that his shoulder harness did not function.
