What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
.5 Hours into the flight, engine throttle control not responding normally. Any reduction in power resulted in a flight idle condition. Pilot left throttle setting at full power and elected to return to vps. Passenger (also a certificated commerical pilot) declared and emergency and announced intention to return to vps. Once pilot thought he was within gliding distance he moved the throttle to flight idle to glide aircraft to the runway. On short final pilot noticed arresting gear in the runway and attempted to stretch the glide beyond the arresting gear which resulted in a hard landing and airplane skidding off of the runway.
