The noncertificated pilot reported that, during the initial climb after takeoff from an off-airport field, he decided to turn the unregistered aircraft toward more favorable terrain to continue the climb. He added that the airplane then encountered a quartering tailwind, and about 30 ft above ground aerodynamically stalled, and impacted a pole and terrain. The airplane sustained substantial damage to the fuselage. The pilot reported that the airplane was near gross takeoff weight, but there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation station, located 12 miles east of the accident, reported that, about 43 minutes before the accident, the wind was from 090° at 8 knots, 10 statute miles visibility, clear skies, temperature 33°C (91°F), dew point 18°C (64°F). The pilot departed the aircraft to the west.
