What happened
The pilot initiated a takeoff from an intersection on the runway. At the time of initiation, only 1400 feet of usable runway remained ahead. After beginning the takeoff roll, the pilot decided to abort the maneuver. However, the aircraft was unable to stop within the remaining distance and continued beyond the end of the paved surface. Upon exiting the runway, the aircraft collided with obstacles located in the overrun area.
The investigation
Review of the aircraft performance charts indicated that a takeoff with no flaps would require significantly more distance than was available. Specifically, the data showed that an aircraft weighing 3000 pounds would need approximately 2000 feet to clear 50-foot obstacles during such a takeoff configuration.
Findings
The primary factor in this accident was the decision to initiate a takeoff from an intersection where the remaining runway length was insufficient for the abort or full stop. The available 1400 feet was less than the required performance distance, leading to the overrun and subsequent collision with obstacles.
