Accidents
Hypoxia Contributed to Fatal Caravan Crash
Cessna 208B Caravan, Naches, Wash., Oct.

Cessna 208B Caravan, Naches, Wash., Oct. 7, 2007–The Board attributed the
fatal crash to the pilot’s failure to maintain adequate airspeed to avoid a stall while maneuvering. Contributing factors were the pilot’s impaired state due to hypoxia, his inadequate pre-flight weather evaluation and his attempted flight into known adverse weather. The pilot’s inadvertent flight into IMC with turbulence at night was listed as an additional cause.

The single-engine turboprop, operated by Kapowsin Air Sports, was destroyed and the commercial pilot and nine passengers killed when the Caravan crashed into terrain during a night flight from Star, Idaho, to Shelton, Wash. The flight was carrying a group of skydivers to their home base after a weekend of
skydiving. The day of the accident, the pilot flew several jump flights and stopped early in the afternoon to prepare the aircraft for the return flight.
