What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The aircraft engine began to run rough and the RPM dropped to 1500 in cruise flight so the pilot circled open fields and when he couldn't keep sufficient altitude he made an emergency landing in a field. The aircraft rolled approximately 200 feet before flipping and coming to rest upside down in the field.
