A contributing factor was the variable wind. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Wind: variable wind](https://openairdocs.org/ntsb-findings/03034025): Environmental issues › Conditions/weather/phenomena · Not specified (probable cause); cases with it: [Weatherly 620B, 1 case](https://openairdocs.org/ntsb-findings/03034025/cases.md?model=9630605), [All aircraft, 113 cases](https://openairdocs.org/ntsb-findings/03034025/cases.md) - [Use of equip/info: aircraft control](https://openairdocs.org/ntsb-findings/02063040): Personnel issues › Task performance · Pilot (probable cause); cases with it: [Weatherly 620B, 3 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md?model=9630605), [All aircraft, 9,295 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight. The defining event best describes what happened. - [Landing-landing roll: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [Weatherly 620B, 2 cases](https://openairdocs.org/ntsb-events/230/sequence.md?model=9630605), [All aircraft, 4,585 cases](https://openairdocs.org/ntsb-events/230/sequence.md) ## Analysis While on landing roll on a private airstrip, the single-engine, tailwheel-equipped airplane encountered a gust of wind. The pilot was not able to correct the airplane's ground track before the airplane encountered soft soil near the edge of the airstrip. The pilot attempted to quickly stop the airplane and applied full brakes. Brake marks and propeller strikes lead to a point where the airplane nosed over. The private airstrip is oriented approximately 020 degrees, and winds in the vicinity were reported as variable from 340 degrees to 050 degrees at 11 knots. ## Factual narrative While on landing roll-out on a private strip, the single-engine, tail wheel equipped airplane encountered a gust of wind. The pilot was not able to correct the airplane's ground track before the airplane encountered soft soil near the edge of the strip. The pilot attempted to quickly stop the airplane and applied full brakes. Brake marks and propeller strikes lead to a point where the airplane nosed over and came to rest in the inverted position. The private strip is oriented approximately 020 degrees and winds in the vicinity were reported as variable from 340 degrees to 050 degrees at 11 knots. ## Aircraft - Registration: [N2035J](https://openairdocs.org/deregistered/N2035J-2017-08-14), registration cancelled 2017-08-14, S/N 1592, built 1995 (OpenAirDocs) - Reported make and model: Weatherly 620B - Registry model: [Weatherly 620B](https://openairdocs.org/model/weatherly-620b) (registry code 9630605) (OpenAirDocs) - Registry engine: [Pratt & Whitney R-985 series](https://openairdocs.org/engine/pratt-whitney-r-985-series) (registry code 52008, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 1592 - Engines: Pratt & Whitney R-985 450 horsepower reciprocating - Damage: Substantial damage - Flight: Aerial application, Part 137 - Registered owner: Joe Burkett - Airworthiness certificate: Special, Restricted (Special) - Departed: Coleman, TX - Destination: Coleman, TX - Airport: runway 020, 4,700 × ft ## Flight crew As NTSB recorded them.
