As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

GLIDER DEPARTED TRUCKEE, CA AIRPORT (TRK) AT 1258PST ON 9/2/18 WITH TWO OCCUPANTS VIA AN AERO TOW.

WATER BALAST TANKS WERE NOT FILLED ON GLIDER.

GLIDER WAS OBSERVED FLYING NORTH TO SOUTH ALONG THE EAST SIDE OF MOUNT ROSE (SLIDE MOUNTAIN) IN WASHOE VALLEY, NV AT APPROXIMATELY 8,000 FT, MSL.

GLIDER WAS OBSERVED ROLLING BACKWARDS.

A LOUD POP WAS HEARD AND THE LEFT INBOARD SECTION OF THE WING WAS OBSERVED DEPARTING THE AIRCRAFT.

THE AIRCRAFT WAS OBSERVED SPINNING LEFT WITH A STEEP NOSE LOW ATTITUDE AND THEN IT CONTACTED THE GROUND AT 1330 PST.

A POST ACCIDENT FIRE CONSUMED THE WRECKAGE AND RESULTED IN A 50 ACRE FOREST FIRE.

THE INBOARD LEFT WING, PART OF THE AILERON AND SMALL PIECES OF THE CANOPY WERE FOUND 5OO METERS NORTH OF THE IMPACT SITE.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB WPR18FA247](https://openairdocs.org/ntsb/WPR18FA247), Sep 2, 2018: Schempp-Hirth Duo Discus T (N22XC), New Washoe City, NV, destroyed, 2 fatal. Probable cause: The pilot’s delayed recovery from an inadvertent spin and/or spiral dive and an exceedance of the glider’s design limit load during recovery, which resulted in an overload failure of both wings.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft 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. For accidents, the NTSB's own investigation is the fuller record.
