On June 19, 1994, about 1145 hours Pacific daylight time, a Payne Foster Glasair, N250CH, collided with two parked aircraft after a bounced landing on the right shoulder of runway 21 at the Hesperia Airport, Hesperia, California. The airplane was being operated by the pilot as a personal flight. The airplane was substantially damaged. The certificated private pilot received minor injuries. The flight originated in Fresno, California. Visual meteorological conditions prevailed at the time. According to a Federal Aviation Administration (FAA) inspector on scene at the time, the pilot experienced a gust of wind and was forced to the right of the approach end of the runway where the left wing collided with the ground. The pilot applied full power in an attempt to go-around. The aircraft flew over and collided with a Cessna 310 (unoccupied) that was parked on the right side of the runway, inflicting minor damage to the right elevator. The aircraft remained airborne and proceeded down the runway. It then veered left across the runway toward the refueling area and collided with a Cessna 172 (N770LW) that was refueling. The FAA inspector said the pilot related to him during the rescue that he did not remember to compensate for density altitude; forgot to lean the fuel mixture for better performance; and, he was caught by a gust of wind at the end of the runway. The temperature at the time was estimated by the pilot to be 100 degrees Fahrenheit with the winds from the southeast at 20 knots. The weather observation at Daggett (about 40 miles to the northeast) was 96 degrees and winds from 050 degrees at 7 knots. The pilot stated in his accident report that there were no mechanical malfunctions with the aircraft prior to the accident.
