Read the full NTSB narrative

According to passengers, the airplane began its takeoff roll at the approach end of the runway, accelerated, lifted off, climbed a few feet, and settled back on the runway. The airplane "swerved" as it slowed and then overran the departure end of the runway and 100 feet of the grass overrun area. Skid marks were observed about 712 feet before the end of the runway. Postaccident examination of the wreckage revealed no preimpact mechanical anomalies. The engine was test run and it operated satisfactorily. Weight and balance calculations revealed the estimated weight of the airplane at takeoff was 3,830 pounds, which was 230 pounds above the maximum allowable gross weight. The accelerate/stop distance calculated for the airplane’s takeoff weight was 2,483 feet. Based on the length of the runway and the calculated accelerate/stop distance, the pilot should have been able to abort the takeoff in time to avoid an overrun.
