He elected to land on runway 17, and while on final approach, the powered glider was high and landed over 1000 ft down the runway. The powered glider overran the departure end of the runway and impacted terrain, resulting in substantial damage to the aft fuselage and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the powered glider that would have precluded normal operation. ## Aircraft - Registration: [N995J](https://openairdocs.org/aircraft/N995J), registered now, S/N 11-083 (OpenAirDocs) - Reported make and model: STEMME GMBH & CO S10-VT - Registry model: [Stemme S10-VT](https://openairdocs.org/model/stemme-s10-vt) (registry code 1130872) (OpenAirDocs) - Registry engine: [Rotax 914 series](https://openairdocs.org/engine/rotax-914-series) (registry code 55575, 4 cycle) (OpenAirDocs) - Category: Glider - Serial number: 11-083 - Year built: 2004 - Airframe hours: 1137.1 - Engines: Rotax 914F2/S1 115 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal; Standard, Utility - Last inspection: Annual, January 9, 2024, 0.6 hours before - Airport: 0E0, Moriarty Municipal Airport, runway 17, 6,201 × 75 ft, asphalt - Equipment: ADS-B, Electronic primary flight display ## Flight crew As NTSB recorded them.
