At about 12:05 MDT, a Piper Cheyenne on a Part 135 passenger flight was damaged during a forced landing near Garden Valley, about 30 minutes after takeoff. The pilot and six passengers were uninjured, while a seventh passenger suffered minor injuries. The pilot reported that, while in cruise configuration, the low fuel pressure lights illuminated and the left engine began to surge. The pilot secured the left engine and executed a forced landing in a open field. Investigators found no fuel aboard the aircraft.
