Contributing to the accident was the sudden wind shift which rendered the aircraft uncontrollable when the aircraft was on final approach to land. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Hard landing, landing - flare/touchdown - weather condition - sudden windshift (cause) - aircraft control - not possible, pilot in command - weather condition - high wind - weather condition - gusts ## Analysis During final approach for landing the 27 horsepower motor glider was subjected to winds which increased from 10 knots to 24 knots with gusts to 37 knots. The landing was hard, causing damage to the wings and bottom of the fuselage. ## Factual narrative On June 14, 1998, at 1930 mountain daylight time, a Schempp-Hirth, 27 horsepower motorized, Ventus CM glider, N94DP, sustained substantial damage during landing at Taos Municipal Airport, Taos, New Mexico. The commercial pilot and sole occupant was not injured. The flight was being operated under Title 14 CFR part 91 and no flight plan was filed. Visual meteorological conditions prevailed for this personal flight which departed Taos at 1415. According to the facility that is repairing the aircraft, both wings and the bottom side of the fuselage sustained substantial damage due to a hard landing. The occurrence was not classified as an accident until this assessment was completed on June 25, 1998. According to the pilot, he returned to land at 1930 and the wind shifted while he was on final approach. The pilot said the wind also increased in velocity and as a result the touchdown was hard and he cut is head on the instrument panel. Recorded wind during the time period of the accident was from 360 degrees magnetic heading at 24 knots with gusts to 37 knots. The landing was being conducted on runway 04. According to the pilot of a Beach Baron, who landed just before the accident occurred, the winds were out of the north at less than 10 knots during his landing. ## Aircraft - Registration: [N94DP](https://openairdocs.org/deregistered/N94DP-2018-04-04), registration cancelled 2018-04-04, S/N 4, built 1989 (OpenAirDocs) - Reported make and model: Schempp-Hirth VENTUS CM - Registry model: [Schempp-Hirth VENTUS CM](https://openairdocs.org/model/schempp-hirth-ventus-cm) (registry code 3800266) (OpenAirDocs) - Registry engine: [NONE](https://openairdocs.org/engine/none) (registry code 00000, none) (OpenAirDocs) - Category: Glider - Serial number: 4 - Airframe hours: 844 - Engines: Solo 2350B/2004 27 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Phillip J.
