# NTSB LAX06CA248: Cessna T210N, N6686N, Truckee, CA, July 22, 2006 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: July 21, 2006, 19:45 local (Jul 22, 2006, 02:45 UTC) - Place: Truckee, CA - Coordinates: 39.319999, -120.139442 - Nearby events: https://openairdocs.org/map.md?lat=39.3200&lon=-120.1394&mi=10 - Phase of flight: [Approach](https://openairdocs.org/ntsb-phases/500) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 6 uninjured - Status: Completed, report November 29, 2006 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 64240 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX06CA248 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/64240/pdf - Page: https://openairdocs.org/ntsb/LAX06CA248 ## Probable cause the pilot's inadequate compensation for the existing wind conditions and failure to maintain an adequate airspeed. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - In flight encounter with weather, approach - vfr pattern - final approach - compensation for wind conditions - inadequate, pilot in command (cause) - weather condition - windshear (contributing factor) - Hard landing, landing - flare/touchdown - airspeed - inadequate, pilot in command (cause) - porpoise/pilot-induced oscillation - encountered, pilot in command (cause) - Nose gear collapsed, landing - roll - landing gear,nose gear - separation ## Analysis The airplane landed hard and the nose landing gear collapsed and separated. According to the pilot, he was landing the airplane in weather conditions he described as light rain, no wind, with thunderstorms in the distance. While on short final the airplane encountered wind shear resulting in a loss of airspeed and an increased rate of descent. The pilot applied power, but the airplane impacted the runway and porpoised 3 to 4 times before the landing gear collapsed. ## Factual narrative On July 21, 2006, at 1945 Pacific daylight time a Cessna T210N, N6686N, was substantially damaged when it landed hard on runway 19 at the Truckee-Tahoe Airport, Truckee, California. The private pilot and five passengers were not injured. The pilot operated the airplane under the provisions of 14 CFR Part 91 as a personal flight. Visual meteorological conditions prevailed and a flight plan was not filed for the cross-country flight, which originated from Concord, California, at 1830. During a telephone interview with the pilot, he stated that their flight was approaching for landing with weather conditions described as light rain, no wind, and thunderstorms in the distance. The pilot's flight was number two for landing and the previous airplane reported encountering no problems during landing. While on short final, his flight encountered wind shear, which resulted in a decreased airspeed and an excessive descent rate. The pilot applied power, but the airplane struck the runway and porpoised 3 to 4 times before the nose landing gear collapsed and separated, damaging the structural members in the nose area. At 1949, the weather observation facility at the Truckee-Tahoe Airport reported the following information: winds from 240 degrees at 5 knots; visibility 10 statute miles; clear sky; temperature 20 degrees Celsius; dew point 01 degrees Celsius; and an altimeter setting of 30.23 inches of mercury. The pilot reported no anomalies with the airplane or engine. ## Aircraft - Registration: [N6686N](https://openairdocs.org/aircraft/N6686N), registered now, S/N 21063146, built 1978 (OpenAirDocs) - Reported make and model: Cessna T210N - Registry model: [Cessna T210N](https://openairdocs.org/model/cessna-t210n) (registry code 2073456) (OpenAirDocs) - Registry engine: [Continental TSIO-520 series](https://openairdocs.org/engine/continental-tsio-520-series) (registry code 17040, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 21063146 - Engines: Teledyne Continental TSIO-520-R 310 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Departed: CCR, Concord, CA - Destination: TRK, Truckee, CA - Airport: TRK, Truckee-Tahoe, runway 19, 4,650 × 75 ft, asphalt ## Flight crew As NTSB recorded them.

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.
