Fatal aviation accident: Cessna 150F near MAPLE (1999-08-06)
Probable cause: the pilot's failure to follow the aircraft's operating checklist and retract the wing flaps for takeoff as specified, as well as the pilot's failure to maintain airspeed (Vso) on initial takeoff climb, which resulted in an inadvertent stall, a spin, and subsequent collision with the terrain. A finding was marihuana in the pilot's blood and urine.
