Neptune Aviation has finished their portion of the process of converting two of the U.S. Forest Service C-23B Sherpa aircraft to civilian SD3-60 certificates. The contract Neptune received last year could involve converting another 13 of the former U.S. Army Sherpas. The USFS expects to use them to haul smokejumpers, personnel, and cargo.
Neptune’s project began at the USFS facility in Ogden, Utah where the first two aircraft were done, but is in the final stages of being moved to the company’s facilities in Missoula, Montana for the remaining aircraft.
Field Aviation in Oklahoma City began the process in October, 2015 of converting the analog cockpits in the Sherpas to glass flight decks using the Garmin G950 system.
