NTSB summary

HISTORY OF FLIGHT On December 12, 1999, about 1235 mountain standard time (MST), a Mooney M20-M, N270BB, was destroyed when it collided with mountainous terrain approximately nine miles northeast of Missoula, Montana. The airplane was registered to and operated by the pilot as an instrument flight rules (IFR) personal flight under the provisions of Title 14 CFR Part 91. The certified private pilot, the sole occupant of the aircraft, was fatally injured. Visual meteorological conditions prevailed at Missoula, and an instrument flight plan was activated. The flight originated from Felts Field, Spokane, Washington, approximately one hour prior to the accident. There was no fire and no report of ELT activation. Flight plan information obtained from Seattle Automated Flight Service Station (AFSS) indicated that the pilot's planned destination was Sioux Falls, South Dakota, (FSD) via Federal Airways (V-2) and direct routing. The flight plan indicated that the aircraft had 6 hours of fuel onboard and that the estimated time en route was 4 hours and 30 minutes. The flight plan also indicated that the pilot's planned altitude was 23,000 feet (FL230). At 1221, 48 minutes after departure, the pilot reported to Salt Lake Center, "... I have no manifold pressure [and] I need vectors to the closest airport." The Air Route Traffic Control Center (ARTCC) instructed the pilot to turn right to a heading of 270 degrees and advised him that the heading change will be a vector to Missoula. Prior to the reported loss of manifold pressure, the aircraft was in level flight at FL250. At 1935, the p

Probable cause
