Aborted Takeoff
A pilot reported that during the ground run on takeoff from a turf runway, he felt severe vibration in the nose gear. He lifted the nose gear off the ground, and at that moment, he perceived a loss of engine power. The pilot then aborted the takeoff attempt. However, the aircraft could not be stopped before it overran the runway and entered the Gulf of Mexico.
Post-Crash Inspection
A post-crash inspection of the aircraft's nose gear and engine revealed no evidence of pre-crash mechanical failure or malfunction. The systems appeared to have been functioning normally prior to the accident.
Wind Conditions
The airport operator stated that at the time of the accident, winds were from the west at approximately 10 knots. The flight departed to the east, resulting in a tailwind component of about 10 knots during the takeoff roll.
Soft-Field Takeoff Technique
According to the airport operator, proper soft-field takeoff technique was not used during the departure. The specifics of the technique employed were not detailed, but the standard procedure for turf runways was not followed.
