A contributing factor was the quartering tailwind. ## Findings NTSB's coded findings; those marked are part of the probable cause. - [Wind: tailwind](https://openairdocs.org/ntsb-findings/03034015): Environmental issues › Conditions/weather/phenomena · Contributed to outcome (probable cause); cases with it: [Tuth Louis RV-3, 1 case](https://openairdocs.org/ntsb-findings/03034015/cases.md?model=05608P3), [All aircraft, 594 cases](https://openairdocs.org/ntsb-findings/03034015/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: [Tuth Louis RV-3, 1 case](https://openairdocs.org/ntsb-findings/01062030/cases.md?model=05608P3), [All aircraft, 184 cases](https://openairdocs.org/ntsb-findings/01062030/cases.md) - [Info processing/decision: decision making/judgment](https://openairdocs.org/ntsb-findings/02041520): Personnel issues › Action/decision · Pilot (probable cause); cases with it: [Tuth Louis RV-3, 1 case](https://openairdocs.org/ntsb-findings/02041520/cases.md?model=05608P3), [All aircraft, 3,098 cases](https://openairdocs.org/ntsb-findings/02041520/cases.md) ## Sequence of events The events NTSB coded, in order, by phase of flight.

The lead airplane requested runway 36 while on a two-mile final. When the lead airplane lost radio communications, the number two airplane then took the lead position. They were told twice by air traffic control to "hasten" their pattern since someone "faster" was behind them. Twice, the controller told someone to quit talking. The lead and number two airplanes landed in before the number three airplane. The pilot of the number three airplane stated that she lost control of the airplane just before touchdown. The left wing was damaged when it struck the grass adjacent to the runway. The airplane then cart wheeled and came to rest upright. The pilot received minor injuries. The pilot stated that winds were from 240 degrees at 8 knots at the time of the accident and that she should not have agreed to use a runway with a quartering tailwind or be "pushed" to hurry between two aircraft. ## Factual narrative A pilot, who was flying the number three airplane, and two other airplanes were en route to the destination airport and on approach to runway 36 (8,002 feet by 150 feet, concrete/grooved).

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.
