From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

On June 9, 2014, the reporting inspector received an electronic mail (email) from the national transportation safety board (NTSB) notifying about a glider accident. The email contained a brief explanation of the event and the pilot?s telephone number and email address. On June 10, 2014, the reporting inspector contacted the pilot by phone. In accordance with the pilot?s statement, on June 6, 2014, another aircraft gave him a tow starting at 2:06 central standard time. Wind condition was down the runway 18 at 8KNOTS, 10+ miles visibility and soarable sky. Before the tow began he went over the procedure for no assist launch with the towing aircraft pilot. Pilot indicated that after completing the takeoff checklist he gave the towing aircraft pilot a signal indicating he was ready. In accordance with the pilot the takeoff preceded nominally, wings level, aileron authority established and gaining speed. Pilot stated: ?just broke ground and noticed the tow plane moving laterally to the east (strong gust or thermal)?. According to the pilot, the towing aircraft corrected and when he was ready for the same, the glider was lifted about 8 feet and the left wing continued to rise. He indicated that he could still see the tow aircraft and immediately applied left full aileron and rudder. He added forward pressure to the stick in order to get back into position. The left wing continued to rise and the tow rope was released as the right turn continued to about 30 degrees. The right turn stopped, stabilized and was beginning to move back towards the tow aircraft. As recovery started the glider exited the area causing an abrupt gain in height and right turn and sank quickly, striking the ground hard resulting in substantial damage to the aircraft. Pilot had no injuries. Review of the photos provided by the pilot revealed that the canopy was destroyed, the instrument panel and empennage ripped off, damage to the vertical fin, rudder, horizontal stabilizer and elevator.

THE LEFT WING CONTINUED TO RISE AND THE TOW ROPE WAS RELEASED AS THE RIGHT TURN CONTINUED TO ABOUT 30 DEGREES. THE RIGHT TURN STOPPED, STABILIZED AND WAS BEGINNING TO MOVE BACK TOWARDS THE TOW AIRCRAFT.
