Contributing factors were the flight instructor's delayed remedial action, and the crosswind conditions. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Wind: crosswind](https://openairdocs.org/ntsb-findings/03034040): Environmental issues › Conditions/weather/phenomena · Not specified (probable cause); cases with it: [Diamond Aircraft Ind DA20-C1, 5 cases](https://openairdocs.org/ntsb-findings/03034040/cases.md?model=2990001), [All aircraft, 1,008 cases](https://openairdocs.org/ntsb-findings/03034040/cases.md) - [Use of equip/info: aircraft control](https://openairdocs.org/ntsb-findings/02063040): Personnel issues › Task performance · Pilot (probable cause); cases with it: [Diamond Aircraft Ind DA20-C1, 37 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md?model=2990001), [All aircraft, 9,295 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md) - [Use of equip/info: aircraft control](https://openairdocs.org/ntsb-findings/02063040): Personnel issues › Task performance · Student/instructed pilot (probable cause); cases with it: [Diamond Aircraft Ind DA20-C1, 37 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md?model=2990001), [All aircraft, 9,295 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md) - [Action: delayed action](https://openairdocs.org/ntsb-findings/02041025): Personnel issues › Action/decision · Pilot (probable cause); cases with it: [Diamond Aircraft Ind DA20-C1, 6 cases](https://openairdocs.org/ntsb-findings/02041025/cases.md?model=2990001), [All aircraft, 894 cases](https://openairdocs.org/ntsb-findings/02041025/cases.md) - [Terrain](https://openairdocs.org/ntsb-findings/03021000): Environmental issues › Physical environment · Not specified; cases with it: [Diamond Aircraft Ind DA20-C1, 1 case](https://openairdocs.org/ntsb-findings/03021000/cases.md?model=2990001), [All aircraft, 267 cases](https://openairdocs.org/ntsb-findings/03021000/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight.

During the final approach to runway 26L, the airplane encountered gusty crosswind conditions. Approximately 15 to 20 above ground level with the student pilot at the airplane controls, the airplane nose was 20 degrees to the right and the wings were level. At that time, the flight instructor took over control of the airplane and applied control inputs to correct for the crosswind. The airplane continued to the right and descended "with no response to my inputs." The instructor then applied full power and attempted a go-around. The airplane "lightly" touched down on the runway, however, continued to the right side of the runway surface and contacted rising terrain. Subsequently, the left main landing gear separated and the airplane came to rest upright off the runway. ## Factual narrative According to the flight instructor and student pilot, they were landing the airplane on runway 26L. Prior to the initial approach, the tower reported the wind was from 280 degrees at 22 knots. During the final approach, the airplane encountered gusty crosswind conditions. Approximately 15 to 20 feet above ground level with the student pilot at the airplane controls, the airplane nose was 20 degrees to the right and the wings were level. At that time, the flight instructor took over control of the airplane and applied control inputs to correct for the crosswind. The airplane continued to the right and descended "with no response to my inputs." The instructor then applied full power and attempted a go-around. The airplane "lightly" touched down on the runway, however, continued to the right side of the runway surface and contacted rising terrain. Subsequently, the left main landing gear separated and the airplane came to rest upright off the runway. The flight instructor and student pilot were not injured. The left wing composite structure was fractured in several areas near the main landing gear attach points. No anomalies were noted with the airframe and engine. ## Aircraft - Registration: [N954DA](https://openairdocs.org/aircraft/N954DA), registered now, S/N C0450, built 2007 (OpenAirDocs) - Reported make and model: Diamond Aircraft Industries DA 20-C1 - Registry model: [Diamond Aircraft Ind DA20-C1](https://openairdocs.org/model/diamond-aircraft-ind-da20-c1) (registry code 2990001) (OpenAirDocs) - Registry engine: [Continental IO-240-B](https://openairdocs.org/engine/continental-io-240-b) (registry code 17177, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: C0450 - Engines: Continental IO-240-B17 reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Doss Aviation IFS - Registered owner: Doss Aviation Inc. - Airworthiness certificate: Standard, Normal - Departed: CO80, Fowler, CO - Destination: PUB, Pueblo, CO - Flight plan: Company VFR - Airport: PUB, Pueblo Memorial, runway 26L, 3,767 × 75 ft, asphalt ## Flight crew As NTSB recorded them.
