# NTSB DEN05CA021: Temco GC-1B, N80791, Angel Fire, NM, November 5, 2004 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: November 5, 2004, 15:15 local (22:15 UTC) - Place: Angel Fire, NM - Coordinates: 36.319999, -105.294166 - Nearby events: https://openairdocs.org/map.md?lat=36.3200&lon=-105.2942&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report January 24, 2005 - Report: Approved by Office Director - Parties: ABQ Flight Standards District Office - NTSB case key (mKey): 60536 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=DEN05CA021 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/60536/pdf - Page: https://openairdocs.org/ntsb/DEN05CA021 ## Probable cause the pilot's failure to maintain directional control and his inadequate compensation for wind. Contributing to the accident was the crosswind. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - flare/touchdown - directional control - not maintained, pilot in command (cause) - compensation for wind conditions - inadequate, pilot in command (cause) - ground loop/swerve - encountered, pilot in command - weather condition - crosswind (contributing factor) - On ground/water encounter with terrain/water, landing - flare/touchdown - terrain condition - ground ## Analysis According to the pilot, during the landing roll on runway 17, he "lost rudder effect and [the] airplane began to weathervane to the right." The pilot added back pressure, "set the tail down," and applied brakes. After several "turns" to the left and right," the airplane ground looped to the left. Both main landing gear collapsed causing substantial damage. According to the pilot, winds at the time of the accident were reported to him, by the UNICOM, as 240 degrees at 14 knots. The pilot stated further that the winds appeared to be from 250 degrees to 260 degrees. In a statement provided by the individual manning the UNICOM, the winds were reported as 225 degrees at 14 knots. The calculated crosswind component was between 12 and 14 knots. ## Factual narrative On November 5, 2004, at approximately 1515 mountain standard time, a Temco GC-1B, N80791, piloted by a private pilot, was substantially damaged when it impacted the runway during landing roll at Angel Fire Airport (AXX), Angle Fire, New Mexico. Visual meteorological conditions prevailed at the time of the accident. The personal flight was being conducted under the provisions of Title 14 CFR Part 91 without a flight plan. The pilot and his passenger reported no injuries. The cross-country flight originated from Dodge City, Kansas, at 1345 central standard time and was en route to AXX. According to the accident report submitted by the pilot, during the landing roll on runway 17, he "lost rudder effect and [the] airplane began to weathervane to the right." The pilot added back pressure, "set the tail down," and applied brakes. After several "turns" to the left and right," the airplane ground looped to the left. Both main landing gear collapsed. The left aileron jammed into the trailing edge of the left wing and the left main wing spar was bent. A postaccident examination of the airplane systems, conducted by the FAA, revealed no anomalies. According to the pilot, winds at the time of the accident were reported to him, by the UNICOM, as 240 degrees at 14 knots. The pilot stated further that the winds appeared to be from 250 degrees to 260 degrees. In a statement provided by the individual manning the UNICOM, the winds were reported as 225 degrees at 14 knots. The calculated crosswind component was between 12 and 14 knots. ## Aircraft - Registration: [N80791](https://openairdocs.org/aircraft/N80791), registered now, S/N 194, built 1946 (OpenAirDocs) - Reported make and model: Temco GC-1B - Registry model: [Temco GC-1B](https://openairdocs.org/model/temco-gc-1b) (registry code 9230108) (OpenAirDocs) - Registry engine: [Continental C125 series](https://openairdocs.org/engine/continental-c125-series) (registry code 17011, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 194 - Airframe hours: 2285 - Engines: Rolls-Royce IO-360-DC 210 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 19, 2004, 30.8 hours before - Departed: DDC, Dodge City, KS - Destination: AXX, Angel Fire, NM - Airport: AXX, Angel Fire, runway 17, 8,900 × 100 ft, asphalt ## Flight crew As NTSB recorded them.
