NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
According to the glider pilot, while being towed during the takeoff roll, the glider encountered a bump and he heard a loud bang. He reported that he was contacted by radio and informed that the aft canopy had separated from the glider. The pilot recalled that although the glider controllability was normal he communicated with the tow airplane pilot, executed one pattern and landed the glider. The pilot reported that during the preflight inspection he failed to properly close and lock the two canopy latches for the aft canopy. The glider sustained substantial damage to the aft canopy and the vertical stabilizer.
The pilot reported that were no mechanical failures or anomalies with any portion of the glider that would have prevented normal flight operations.
