Contributing to the accident were gusting unfavorable winds, the short runway, and rocks off the departure end of the strip. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Airport facilities/design: runway/landing area length](https://openairdocs.org/ntsb-findings/03017037): Environmental issues › Operating environment · Not specified (probable cause); cases with it: [Aviat A-1C-200, 1 case](https://openairdocs.org/ntsb-findings/03017037/cases.md?model=2210411), [All aircraft, 34 cases](https://openairdocs.org/ntsb-findings/03017037/cases.md) - [Wind: gusts](https://openairdocs.org/ntsb-findings/03034045): Environmental issues › Conditions/weather/phenomena · Not specified (probable cause); cases with it: [Aviat A-1C-200, 5 cases](https://openairdocs.org/ntsb-findings/03034045/cases.md?model=2210411), [All aircraft, 1,199 cases](https://openairdocs.org/ntsb-findings/03034045/cases.md) - [Performance/control parameters: crosswind correction](https://openairdocs.org/ntsb-findings/01062030): Aircraft › Aircraft oper/perf/capability · Not attained/maintained (probable cause); cases with it: [Aviat A-1C-200, 1 case](https://openairdocs.org/ntsb-findings/01062030/cases.md?model=2210411), [All aircraft, 184 cases](https://openairdocs.org/ntsb-findings/01062030/cases.md) - [Performance/control parameters: airspeed](https://openairdocs.org/ntsb-findings/01062010): Aircraft › Aircraft oper/perf/capability · Incorrect use/operation (probable cause); cases with it: [Aviat A-1C-200, 2 cases](https://openairdocs.org/ntsb-findings/01062010/cases.md?model=2210411), [All aircraft, 1,681 cases](https://openairdocs.org/ntsb-findings/01062010/cases.md) - [Airport facilities/design](https://openairdocs.org/ntsb-findings/03017000): Environmental issues › Operating environment · Not specified (probable cause); cases with it: [Aviat A-1C-200, 1 case](https://openairdocs.org/ntsb-findings/03017000/cases.md?model=2210411), [All aircraft, 52 cases](https://openairdocs.org/ntsb-findings/03017000/cases.md) - [Performance/control parameters: descent/approach/glide path](https://openairdocs.org/ntsb-findings/01062040): Aircraft › Aircraft oper/perf/capability · Not attained/maintained (probable cause); cases with it: [Aviat A-1C-200, 1 case](https://openairdocs.org/ntsb-findings/01062040/cases.md?model=2210411), [All aircraft, 809 cases](https://openairdocs.org/ntsb-findings/01062040/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight.

He said that while focusing on compensating for those winds, he failed to slow the airplane sufficiently. After touchdown, the airplane ran off the end of the airstrip, encountered rocks, and nosed over onto its back. ## Factual narrative During the landing roll at a 1,000 foot long remote dirt airstrip, the pilot encountered gusting winds that varied in the their direction. While focused on compensating for the unfavorable winds, the pilot failed to slow the airplane sufficiently to ensure that it could be stopped prior to reaching the end of the airstrip. The airplane therefore overran the end of the airstrip, impacted a number of large rocks, and flipped over onto its back. The accident sequence resulted in damage to the top of the vertical stabilizer, and a permanent bend in both of the lift struts on the left side of the airplane. ## Aircraft - Registration: [N134DD](https://openairdocs.org/aircraft/N134DD), registered now, S/N 3015, built 2008 (OpenAirDocs) - Reported make and model: Aviat A-1C-200 - Registry model: [Aviat A-1C-200](https://openairdocs.org/model/aviat-a-1c-200) (registry code 2210411) (OpenAirDocs) - Registry engine: [Lycoming IO-360-A1D6](https://openairdocs.org/engine/lycoming-io-360-a1d6) (registry code 41822, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 3015 - Engines: Lycoming IO-360-A1D6 reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: John L.
