What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot said he departed the Spanish Fork airport on a flight to evaluate the need to install a rudder trim tab on the experimental aircraft and also to acquire more time on the aircraft that would allow him to have the flight area restriction removed. Upon returning to the Spanish Fork airport and entering a downwind leg for runway 30, the engine began to stutter. He said he switched to the left fuel tank, but the engine continued to stutter and he switched back to "both" tanks. To keep the engine running he had to have the throttle setting quit high. When he got down ready to land, the aircraft was still developing a lot of speed and he overshot the runway and ended up in an open field about 1 mile beyond runway 30. The aircraft didn't finally get stopped until it encountered a ditch. This is a final report.
