What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
As reported by pilot, right after rotation he realized that his rate of climb was only 500 fpm, instead of the expected 1600. The engine started popping and backfiring, and the pilot elected to return to the airport, but upon realizing that he would be unable to reach the airport, he decided to land in a pasture about one mile short of the runway. Aircraft sustained minor damage, due to collision with an electric fence, which caused the aircraft to nose over, no injuries.
