Circumstances:
On January 27, 2001, about 1737 mountain standard time, a Raytheon (Beechcraft) Super King Air 200, N81PF, owned by North Bay Charter, LLC, and operated by Jet Express Services, crashed into rolling terrain near Strasburg, Colorado. The flight was operating on an instrument flight rules (IFR) flight plan under 14 Code of Federal Regulations (CFR) Part 91. The flight departed about 1718 from Jefferson County Airport (BJC), Broomfield, Colorado, with two pilots and eight passengers aboard. The pilot who occupied the left seat in the cockpit was solely responsible for the flight. The pilot who occupied the right seat in the cockpit, referred to in this report as the "second pilot," was not a required flight crewmember. N81PF was one of three airplanes transporting members of the Oklahoma State University (OSU) basketball team and associated team personnel to Stillwater Regional Airport (SWO), Stillwater, Oklahoma, after a game at the University of Colorado at Boulder that afternoon. All 10 occupants aboard N81PF were killed, and the airplane was destroyed by impact forces and a post crash fire. Instrument meteorological conditions (IMC) prevailed at the time of the accident.
Probable cause:
The pilot’s spatial disorientation resulting from his failure to maintain positive manual control of the airplane with the available flight instrumentation. Contributing to the cause of the accident was the loss of a.c. electrical power during instrument meteorological conditions.
Final Report:

Circumstances:
The pilot departed Front Range Airport (elevation 5512 feet) at approximately 2008, climbed to 7,000 feet msl, accelerated to 270 knots, and requested his IFR clearance. Weather at the time of N950TT's departure was 500 feet overcast; witnesses reported the tops of the thin cloud condition were 8,500 feet msl and it was very dark on top (no stars or moon). The pilot made several changes in airspeed and climb rate until radar indicated that he had entered an 8,500 fpm decent. The pilot reported to ATC that he had 'stalled' the airplane. Radar indicated that he then climbed at 7,500 fpm until his estimated airspeed was 10 knots, and then subsequently descended again at 8,400 fpm until he impacted the frozen ground. The pilot had flown 4 times for 7 hours in the previous 40 days. Five airline pilots, each of who had 3,000 to 5,000 hours in Swearingens, stated individually that even though the airplane is single pilot certified, they believed that 'its a two pilot airplane--because the work load is too high.'
Probable cause:
The pilot inadvertently stalling the airplane and his subsequent spatial disorientation which prevented him from maintaining airplane control. Factors were excessive workload on the pilot and the dark night light conditions.
