NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
After getting confirmation from the pilot who took off before him that the wind wasn't that bad, the pilot departed on Runway 17. During the initial climbout the pilot encountered a windshear condition, as the headwind changed to a 20 knot tailwind. Approaching rising terrain and at an altitude of approximately 60 to 80 feet above the ground and not climbing, the pilot elected to abort the takeoff. After retarding the throttle to idle the airplane subsequently impacted the ground "very hard", causing both wheels to separate from both main landing gear, the nose gear folding back into the firewall, and the top two engine mounts separating. There was no postcrash fire and all occupants exited the airplane without injury. The pilot indicated there were no anomalies with the airplane prior to or during the departure, and that the wind at the time of departure was from 170 degree at 10 knots, gusting to 30 knots. The pilot stated that he felt he should have delayed his takeoff for 1 to 2 hours, as cooler temperatures and calmer winds might have prevailed. It was also noted that although the pilot had recently operated into and out of the airstrip, this was the first time he had attempted taking off on Runway 17. The Airport/Facility Directory cautions against taking off on Runway 17, paying particular attention to density altitude, turbulence, and mountain flying proficiency.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's improper preflight planning/preparation during takeoff. A factor was the windshear.
