# NTSB ATL07CA020: Cessna 190, N195AB, Chattanooga, TN, November 21, 2006 - Type: NTSB accident investigation - Classification: Accident · No injuries · Data collection · Final report - Date: November 21, 2006, 17:42 local (22:42 UTC) - Place: Chattanooga, TN - Coordinates: 35.034999, -85.203613 - Nearby events: https://openairdocs.org/map.md?lat=35.0350&lon=-85.2036&mi=10 - Phase of flight: [Takeoff](https://openairdocs.org/ntsb-phases/300) (OpenAirDocs' grouping) - Highest injury: No injuries - Injuries: 3 uninjured - Status: Completed, report February 26, 2007 - Report: Approved by Office Director - Parties: Nashville FSDO-03 - NTSB case key (mKey): 64905 - NTSB case page: https://web.ntsb.gov/investigations/?ntsbnumber=ATL07CA020 - NTSB report (PDF, downloads): https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/64905/pdf - Page: https://openairdocs.org/ntsb/ATL07CA020 ## Probable cause The pilot's failure to maintain directional control on takeoff resulting in a collapse of the left main landing gear when the airplane swerved. A factor in the accident was wake turbulence from a landing airplane. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, takeoff - roll/run - weather condition - crosswind - weather condition - gusts - wake turbulence - encountered, pilot in command (contributing factor) - directional control - not maintained, pilot in command (cause) - ground loop/swerve - inadvertent, pilot in command - Gear collapsed, takeoff - roll/run - landing gear,main gear - overload - landing gear,main gear - collapsed ## Analysis The pilot was cleared for takeoff and was advised the winds were 360 degrees at 11 knots gusting to 19 knots. In addition the pilot was provided a wake turbulence caution for a regional jet that had just landed. The pilot taxied onto the runway and applied power to begin the takeoff roll. The tail of the airplane went to the right and the nose of the airplane went to the left. The pilot applied right rudder to correct and the airplane was slow to the correction. The pilot reduced power and the airplane moved back to the right. Before the airplane reached centerline of the runway, the pilot lost directional control of the airplane. The airplane went to the right and the left wing began to dip. The left main landing gear separated and the airplane came to a complete stop on the runway centerline. The pilot stated, "I believe the wake turbulence generated by the landing regional jet was transmitted back down the runway by the prevailing wind conditions, and the effect of the wake turbulence on the aircraft overrode my appropriate directional control inputs." ## Factual narrative On November 21, 2006, at 1742, eastern standard time, a Cessna 190, N195AB, registered to a private owner, operating as a 14 CFR Part 91 personal flight, collapsed a left main landing gear on take off roll at Lovell Field, Chattanooga, Tennessee. Visual meteorological conditions prevailed and no flight plan was filed. The airplane received substantial damage. The commercial pilot and two passengers reported no injuries. The flight was originating at the time of the accident on November 21, 2006. The pilot stated he obtained taxi clearance to runway 02. He completed an engine run up and no anomalies were noted. He contacted tower for clearance to take off. The controller informed him to hold short for a regional jet on final approach. The regional jet landed, the controller informed the pilot the winds were 360 degrees at 11 knots gusting to 19 knots, provided a wake turbulence caution for the landing jet, and cleared the pilot for take off. The pilot taxied the airplane into position and began his take off roll by adding full power. During the take off roll the tail of the airplane went to the right and the nose of the airplane went to the left. The pilot applied right rudder to correct and the airplane was slow to the correction. The pilot reduced power and the airplane moved back to the right. Before the airplane reached centerline of the runway, the pilot lost directional control of the airplane. The airplane went to the right and the left wing began to dip. The left main landing gear separated and the airplane came to a complete stop on runway centerline. The pilot stated, "I believe the wake turbulence generated by the landing regional jet was transmitted back down the runway by the prevailing wind conditions, and the effect of the wake turbulence on the aircraft overrode my appropriate directional control inputs." ## Aircraft - Registration: [N195AB](https://openairdocs.org/aircraft/N195AB), registered now, S/N 7794, built 1952 (OpenAirDocs) - Reported make and model: Cessna 190 - Registry model: [Cessna 190](https://openairdocs.org/model/cessna-190) (registry code 2072902) (OpenAirDocs) - Registry engine: [Continental W670 series](https://openairdocs.org/engine/continental-w670-series) (registry code 17018, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 7794 - Airframe hours: 4944 - Engines: Jacobs R755-A2 300 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Julius Y.

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.
