Incident Overview
During a takeoff attempt on a 2,300-foot grass airstrip, the pilot experienced sluggish acceleration and aborted the takeoff. The aircraft collided with a tree beyond the end of the runway.
Pilot's Account
The pilot reported performing an engine run-up before departure, with no discrepancies noted. He positioned the airplane on runway 17, facing into a right quartering tailwind from 310 degrees at 8 knots. Upon applying full throttle, the engine rpm reached the red line early in the takeoff roll. At approximately midfield, the acceleration felt sluggish. The pilot continued the roll to about two-thirds down the runway, with the tailwheel still on the ground, then decided to abort. He was unable to stop the aircraft before it struck a tree beyond the airstrip.
Investigation Findings
Post-accident examination revealed that the magnetos were not properly timed. Additionally, there were indications that the carburetor and accelerator pump were not functioning properly. These issues likely affected engine performance during the takeoff roll.
