Circumstances
Just after lifting off from Runway 18 at an altitude of 50 feet, the pilot encountered a windshear condition accompanied by a downdraft. Simultaneously, the stall warning horn activated, and the aircraft ceased to climb. The density altitude for the takeoff, conducted in a 90-degree crosswind, was calculated at 8,700 feet.
Pilot Actions
The pilot attempted once more to accelerate the aircraft to a safe gear and flap retraction speed and to resume climbing, but the aircraft did not respond. Concerned about the ability to clear trees and higher terrain beyond the departure end of the runway, the pilot decided to abort the takeoff.
Outcome
Despite the abort, the pilot was unable to stop the aircraft before it overran the departure end of the 8,544-foot-long runway. The aircraft subsequently collided with an airport boundary fence.
