What happened
The pilot attempted departure from runway 22 at a private airstrip located in an area characterized by gently rolling hills. During the takeoff roll, there was a light quartering tailwind. The aircraft was unable to achieve a sufficient climb gradient. In an effort to avoid rising terrain, the pilot initiated a gradual right turn and opened the dump gate to reduce the aircraft's weight.
The aircraft subsequently touched down on a hill at the end of the runway, bounced back into the air, and landed while traveling up the next hill. This sequence led to a ground loop that resulted in damage to the right wing.
Weather observations from a reporting facility 7 nautical miles south of the accident site indicated winds of 080 degrees at 14 knots at 0753, increasing to 100 degrees at 17 knots by 0853. The pilot reported that there were no mechanical failures or malfunctions present in the aircraft during the event.
