On January 20, 1999, at 1527 mountain standard time, a Cessna P210N, N79NL, was destroyed when it broke up in flight and collided with terrain in the Sandia Mountain Wilderness Area, near Albuquerque, New Mexico. The instrument rated private pilot and two passengers were fatally injured. Visual meteorological conditions prevailed at the accident site, but the pilot reported being in instrument meteorological conditions. An IFR flight plan had been filed for the personal flight being conducted under Title 14 CFR Part 91. The flight originated in Scottsdale, Arizona (SDL), at 1243 Pacific standard time (Pst), and was en route to Wichita, Kansas (ICT).
The pilot reported a dual vacuum pump failure while flying IFR at FL220. Despite having a standby electric artificial horizon, aircraft control was lost during the pilot's attempt to descend to 13,000 feet (reported cloud base). The airframe was overstressed and the right wing failed. Laboratory examination of the vacuum-driven gyroscopes disclosed no evidence of high rotation at impact. Both vacuum pumps bore signatures indicative of failure prior to impact. Not enough of the check valve manifold remained to determine its operational status.
Probable Cause: Total failure of the vacuum system, and failure of the pilot to maintain aircraft control, resulting in wing spar failure. Factors were the pilot's spatial disorientation, and his exceeding the design stress limits of the airplane.
