A factor was the check airman’s inadequate supervision. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Performance/control parameters: directional control](https://openairdocs.org/ntsb-findings/01062020): Aircraft › Aircraft oper/perf/capability · Not attained/maintained (probable cause); cases with it: [Cessna 207A, 2 cases](https://openairdocs.org/ntsb-findings/01062020/cases.md?model=2073605), [All aircraft, 3,958 cases](https://openairdocs.org/ntsb-findings/01062020/cases.md) - [Runway/land/takeoff/taxi surface: snow/slush/ice covered surface](https://openairdocs.org/ntsb-findings/03023015): Environmental issues › Physical environment · Effect on equipment; cases with it: [Cessna 207A, 3 cases](https://openairdocs.org/ntsb-findings/03023015/cases.md?model=2073605), [All aircraft, 219 cases](https://openairdocs.org/ntsb-findings/03023015/cases.md) - [Use of equip/info: aircraft control](https://openairdocs.org/ntsb-findings/02063040): Personnel issues › Task performance · Pilot (probable cause); cases with it: [Cessna 207A, 11 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md?model=2073605), [All aircraft, 9,295 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md) - [Wind: crosswind](https://openairdocs.org/ntsb-findings/03034040): Environmental issues › Conditions/weather/phenomena · Effect on operation; cases with it: [Cessna 207A, 4 cases](https://openairdocs.org/ntsb-findings/03034040/cases.md?model=2073605), [All aircraft, 1,008 cases](https://openairdocs.org/ntsb-findings/03034040/cases.md) - [Action: delayed action](https://openairdocs.org/ntsb-findings/02041025): Personnel issues › Action/decision · Instructor/check pilot (probable cause); cases with it: [Cessna 207A, 2 cases](https://openairdocs.org/ntsb-findings/02041025/cases.md?model=2073605), [All aircraft, 894 cases](https://openairdocs.org/ntsb-findings/02041025/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight.

The pilot said that her approach to Runway 33, a 35-foot wide, 2,200 ft long, ice-covered runway, required a correction for a strong right crosswind. She added that the airport windsock was frozen in place, making it difficult to discern the wind velocity and direction. She reported that during the landing roll, the airplane began to veer to the left of the runway center. She said that the chief pilot/check airman then took control of the airplane to correct the veer, but the strong crosswind continued to push the airplane to the left on the ice-covered runway. The airplane subsequently collided with a snow berm on the left side of the runway, resulting in substantial damage to the right wing. The pilot reported that there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation. During a follow up conversation with the operator’s director of operations, he said that the chief pilot/check airman was on board the accident flight to provide additional OE to a recently hired pilot due to icy runway conditions and a strong crosswind at the destination airport. This was the pilot’s first flight to the remote village. ## Aircraft - Registration: [N9996M](https://openairdocs.org/aircraft/N9996M), registered now, S/N 20700779, built 1984 (OpenAirDocs) - Reported make and model: CESSNA 207 - Registry model: [Cessna 207A](https://openairdocs.org/model/cessna-207a) (registry code 2073605) (OpenAirDocs) - Registry engine: [Continental IO-520-F](https://openairdocs.org/engine/continental-io-520-f) (registry code 17237, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 207007779 - Year built: 1984 - Engines: Continental IO-520-F 285 horsepower reciprocating - Damage: Substantial damage - Flight: Business, Part 135 - Operator: Yute Air Commuter - Registered owner: Yr-Aircraft Leasing LLC - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, January 9, 2023, 33.6 hours before - Departed: BET, Bethel, AK - Destination: Same as departure - Flight plan: Company VFR - Airport: PAEW, Newtok, runway 33, 2,200 × 35 ft, snow - Equipment: Electronic flight bag or handheld device ## Flight crew As NTSB recorded them.
