The pilot reported that, prior to takeoff from a high altitude, 1,700 ft dirt airstrip with a 9,200 ft density altitude, he set the flaps to 20°, held the brakes, and ran the engine up to full power. He released the brakes, pulled back on the yoke, and the airplane accelerated. The pilot reported that the takeoff roll "seemed longer and slower than usual" and about two-thirds of the way down the runway the airspeed was 45 knots. Near the end of the runway, the airplane momentarily became airborne about 15 ft above the ground, drifted to the right, and settled back onto the ground. The airplane struck a sage bush, skidded left, the left landing gear collapsed, and the left wing impacted terrain.

The airplane sustained substantial damage to the left wing and left elevator.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
