What happened
During a towed takeoff operation, the glider experienced an unexpected deployment of its spoilers while airborne. The tow aircraft released the glider at approximately 300 feet above ground level after the spoilers had already opened. Despite the premature spoiler extension, the pilot attempted to control the descent and ultimately landed in a wooded area without retracting the spoilers.
The investigation
Following the incident, two Federal Aviation Administration inspectors examined the glider's flight control systems. They specifically tested the operation of the spoilers to determine if a mechanical defect was responsible for the premature deployment. The inspection concluded that the spoiler system functioned normally and showed no signs of malfunction or unintended activation mechanisms.
Findings
The primary factor in this accident was the uncommanded opening of the spoilers during the critical early phase of flight. This event significantly degraded the glider's lift-to-drag ratio, making it impossible to maintain altitude or execute a safe landing at the available height. The investigation confirmed that the equipment itself was operating within normal parameters, suggesting the deployment may have been triggered by aerodynamic forces or an external factor not identified during the post-accident inspection.
