What happened
The pilot was operating a personal flight from Discovery Bay. During the takeoff roll, the aircraft reached an indicated airspeed of 70 mph. At this point, the pilot observed boats approaching in the vicinity. In response to this hazard, the pilot abruptly pulled back on the control wheel, initiating a premature lift-off before the aircraft had achieved sufficient speed for a safe climb.
The airplane responded by rapidly raising into the air but quickly entered a stall condition. The incident was directly linked to the pilot's decision to abort the takeoff roll without first ensuring the departure area was clear of obstacles or watercraft.
The investigation
Examination of the flight dynamics indicated that the aircraft stalled due to the abrupt pitch-up maneuver performed at an airspeed below the recommended rotation speed. The premature lift-off prevented the aircraft from building the necessary kinetic energy to sustain flight.
Findings
The primary contributing factor was the pilot's failure to adequately look out and verify that the departure area was clear of boats before beginning the takeoff roll. This lack of situational awareness led to an emergency maneuver that exceeded the aircraft's performance capabilities at that specific phase of flight.
