What happened
Following an all-day flight originating from Vero Beach, Florida, the pilot diverted from the intended destination to an alternate airport at Twin Falls, Idaho. The pilot attempted a coupled ILS approach; however, during this initial attempt, the autopilot disengaged, resulting in a missed approach.
The pilot then elected to hand-fly a second approach attempt after being unable to reengage the autopilot. During this second attempt, the aircraft descended below the glide path and impacted terrain. The impact occurred in a level plowed field, causing the aircraft to roll over.
At the time of the accident, weather conditions were characterized by one-half mile visibility and a cloud layer that was 200 feet obscured. Following the impact, the pilot attempted to use his radios and discovered the ELT was not transmitting, prompting him to manually activate the ELT.
The pilot was the sole occupant and was not injured.
