What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(.4) While on takeoff roll from a 2,250 foot long Private air strip the aircraft became airborne then settled back to the ground off the end of the departure runway. The runway was dirt surface and the pilot was making his takeoff to the east. Wind at the time was from 290 degrees at 10 knots with gusts to 17 knots. Aircraft performance data provided information that the aircraft was within 70 pounds of its maximum certificated gross weight and that the takeoff chart upper limit was 7,000 foot density altitude. The actual density altitude was 7,700 feet. According to the chart, which was based on a hard surface runway, no wind, and the aircraft at maximum certificated gross weight, the takeoff roll should have been 1,750 feet. The chart also stated that extending the curves above the 7,000 foot upper limit was not permissible. The pilot said he thought he encountered a wind shear during rotation.
