Accident Summary
A pilot and three passengers were climbing through 9,500 feet to fly over a mountain when they encountered a severe downdraft. The pilot reported being unable to clear the mountain peak and made a forced landing straight ahead, citing fear of a stall or spin into the trees. During the landing, the airplane slid approximately 100 feet, which resulted in the separation of the fixed landing gear and inward crushing of the fuselage bottom.
