What happened
During the first flight of the day for both the pilot and the glider, a takeoff was initiated from a position midway down runway 23L. After the aircraft reached approximately 10 feet of altitude, the student pilot heard a metallic flapping sound. Suspecting a potential structural issue, the pilot executed a release from the tow plane immediately after liftoff.
While attempting to locate a suitable landing area, the glider struck the ground and bounced. The aircraft then collided with a cactus plant approximately 1,200 feet from the runway, causing the pilot to lose control. The glider subsequently struck a second cactus with its right wing and entered a spin, eventually colliding with terrain. The accident resulted in substantial damage to the aircraft; the pilot was not injured.
The investigation
A post-flight examination of the aircraft identified a loose wing root gap cover fairing. A ground witness reported seeing the fairing become detached during the takeoff ground roll. Additionally, an instructor who had operated the same glider the previous week noted that while the fairing appeared secure during preflight, it had come loose during flight. The instructor stated that the loose fairing did not affect the aircraft's handling characteristics during their previous uneventful landing.
