Approach and Landing
The pilot reported using a slightly higher than normal approach speed with partial flap extension because of turbulence and wind gusts up to 25 knots. After crossing the threshold at 20 to 30 feet above ground level, the flare resulted in what the pilot described as a long float prior to touchdown.
Aborted Landing and Runway Excursion
Immediately after touchdown, a gust of wind from the right caused the aircraft to drift left. The pilot initiated an aborted landing as it became evident that the left wheel would leave the runway. The aircraft continued across rough terrain, collapsing all three landing gear before coming to rest.
Runway Evidence
Examination of the runway revealed skid marks where the aircraft departed the paved surface.
Density Altitude
Density altitude was calculated to be 7,615 feet.
