# NTSB LAX02LA011: Cessna A185E, N7711L, Winnemucca, NV, October 21, 2001 - Type: NTSB accident investigation - Classification: Accident · No injuries · Limited investigation · Final report - Date: October 21, 2001, 11:30 local (18:30 UTC) - Place: Winnemucca, NV - Coordinates: 40.896667, -117.805831 - Nearby events: https://openairdocs.org/map.md?lat=40.8967&lon=-117.8058&mi=10 - Phase of flight: [Landing](https://openairdocs.org/ntsb-phases/550) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 2 uninjured - Status: Completed, report September 29, 2004 - Report: Approved by Office Director - Parties: Federal Aviation Administration - NTSB case key (mKey): 53676 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=LAX02LA011 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/53676/pdf - Page: https://openairdocs.org/ntsb/LAX02LA011 ## Probable cause The pilot's inadequate compensation for the wind conditions, failure to maintain directional control and use of excessive braking, which resulted in the airplane nosing over. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - weather condition - gusts - compensation for wind conditions - inadequate, pilot in command (cause) - directional control - not maintained, pilot in command (cause) - ground loop/swerve - encountered, pilot in command - Nose over, landing - roll - brakes(normal) - excessive, pilot in command (cause) ## Analysis The airplane ground looped and nosed over during landing roll after encountering gusty crosswind conditions. The pilot was landing the airplane to the northwest. As the airplane was rolling out, the tail wheel equipped airplane swerved to the left resulting in the right wing impacting the ground. The pilot applied right rudder and brake to straighten the airplane. Once the airplane was straight, it nosed over due to excessive braking. The wind was out of the west at 7 knots with gusts to 15 knots. ## Factual narrative On October 21, 2001, about 1130 Pacific daylight time, a Cessna A185E tail wheel equipped airplane, N7711L, nosed over following a loss of directional control during the landing roll at Winnemucca, Nevada. The airplane was registered to, and operated by, the pilot as a personal flight under the provisions of 14 CFR Part 91. Neither the private pilot nor his passenger was injured. The airplane sustained substantial damage. Visual meteorological conditions prevailed, and a flight plan had not been filed. The local flight originated at Winnemucca approximately 1 hour prior to the accident, and was terminating at the time of the accident. According to the pilot's written statement, during the landing roll on runway 32, the airplane swerved to the left causing the right wing to impact the ground. The pilot applied right rudder and brake, which straightened the airplane. The pilot indicated that braking resulted in the airplane nosing over and coming to rest inverted. At 1156, the weather observation facility located at the airport reported that the wind was from 270 degrees at 7 knots with gusts to 15 knots. The pilot had owned the same airplane for 30 years and had accumulated 1,570 hours of flight time in the airplane. The Federal Aviation Administration inspector stated that there were no mechanical malfunctions with the airplane. ## Aircraft - Registration: [N7711L](https://openairdocs.org/aircraft/N7711L), registered now, S/N 185-1521, built 1969 (OpenAirDocs) - Reported make and model: Cessna A185E - Registry model: [Cessna A185E](https://openairdocs.org/model/cessna-a185e) (registry code 2072818) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 185-1521 - Airframe hours: 3029 - Engines: Teledyne Continental IO-520-D9 285 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Douglas E.
