NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The pilot of the twin-engine, turbine-powered airplane reported that, while providing flights for skydivers throughout the day, he had a potential new hire pilot flying with him in the right seat. He added that, on the eighth flight of the day, the new pilot was flying during the approach and “approximately 200’ [ft.] south from the threshold of [runway] 15 at approximately 15 feet AGL [above ground level] the bottom violently and unexpectedly dropped out. [He] believe[d] some kind of wind shear caused the aircraft [to] slam onto [the] runway and bounce into the air at a 45 to 60-degree bank angle to the right.” The prospective pilot then said, “you got it.” The pilot took control of the airplane and initiated a go-around by increasing power, which aggravated the “off runway heading.” The right wing contacted the ground, the airplane exited the runway to the right and impacted a fuel truck, and the right wing separated from the airplane. The impact caused the pilot to unintentionally add max power, and the airplane, with only the left engine functioning, ground looped to the right, coming to rest nose down.
The airplane sustained substantial damage to the fuselage and right wing.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
The automated weather observation system about 8 nautical miles from the accident site reported that, about the time of the accident, the wind was from 280° at 7 knots, visibility 10 statute miles, few clouds at 20,000 ft agl, temperature 86°F, dew point 45°F, and altimeter 29.81 inches of mercury. The pilot landed on runway 15.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • The prospective pilot’s improper landing flare and the pilot’s delayed remedial action to initiate a go-around, which resulted in a runway excursion.
