What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot stated that prior to takeoff and during the engine performance check, the left and right magnetos checked out okay, but the engine ran rough. He applied carburetor heat for awhile and the engine smoothed out. He taxied out onto runway 05. During takeoff the engine continued to run rough and the stall warning horn was heard. He stated that he had planned to abort the takeoff but the aircraft started to lift off the runway and he was at a point of no return. As the pilot continued to climb out the engine started losing power and the stall warning horn was getting louder. The pilot immediately pulled the carburetor heat level and the engine RPM dropped. The pilot made a forced landing in a field north of the airport. During landing the nose wheel stuck in the mud and the airplane flipped over and landed inverted. The airplane incurred substantial damage with one student pilot on board and minor injuries to the pilot. The on scene investigation revealed that the airplane's main spar was substantially damaged. The nose landing gear collapsed and the front part of the engine was substantially damaged, the cockpit and fuselage buckled resulting in major damage to the airplane.
