Descripción:
An electrical short circuit caused an unwanted extension of the ground and flight spoilers during a training flight. Control was lost; the aircraft made several 360deg rolls and then dove into a swampy area.

PROBABLE CAUSE: "An unwanted extension of the ground and flight spoilers, which resulted in a loss of control at an altitude from which recovery could not be made. The ground spoilers probably deployed because of a hot electrical short in the spoiler extend circuitry. Whereas the spoilers probably deployed symetrically, the left ground spoiler actuator failed in flight and caused a loss of lateral control. The subsequent logs of pitch control was caused by the full nosedown elevator trim tab position and the high aircraft speed."
