What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
According to the PIC, the aircraft loaded 3 passengers and luggage. The fuel on board was 100 gallons. Aircraft was 900 pounds below mgw. N66NC taxied for takeoff on runway 29 and conducted a normal pre-takeoff check in the run-up area.
08:24 While conducting surveillance at Vance Brand Airport, (lmo) I observed an aircraft departing runway 29. I was approximately half way down the runway facing nw when I heard the aircraft departing. I watched as the aircraft continued down the runway past my position, and I noted that he should have become airborne by that time. He continued down the runway and lifted slightly toward the end of the runway. He then descended, stuck the ground several times and spun clockwise. He was lost momentarily in a cloud of dust, then smoke began to appear. Emergency personnel responded to the location and began transporting passengers to the hospital.
