What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
As stated by the pilot I departed 7S5 on runway 34. About 3 miles north I noticed an irregularity with the engine/propeller so I did a 180 and headed back. The engine started revving up and the propeller was windmilling so I picked a field and landed the airplane.
Upon landing there was irrigaiton pipe that was not seen during landing seleciton. The aircraft langing gear hit the irrigation pipe and flipped upside down. During teardown it was found that a gear in the gear box between engine and propeller had broken into four pieces.
