No fatalities • Lake City, CO, United States

Probable cause

The pilot's failure during takeoff to attain sufficient airspeed for conditions, and to maintain yaw control and a positive rate of climb, resulting in a loss of directional control, an uncontrolled descent, and collision with trees and terrain.

— NTSB Determination

Accident narrative

The pilot of the tailwheel-equipped airplane was departing from a mountain airport situated in a valley. The pilot reported that during takeoff, he rotated about 52-54 miles per hour, and about 20 feet above the ground, a strong crosswind from the left pushed the airplane to right of the runway centerline. The pilot attempted to overcome the effect of the wind with control inputs, but the airplane collided with trees on the right side of the runway. The airplane sustained substantial damage to the wings, fuselage, and empennage.

An FAA inspector who went to the accident site reported that the pilot rotated approximately 400 feet and impacted trees about 621feet from where the takeoff roll was initiated. The FAA inspector estimated there was at least an additional 2,000 feet of useable runway remaining. The field elevation was 9,300 feet MSL and density altitude was calculated as 12,600 feet. The performance charts for this airplane stop at 8000 feet and required extrapolation for the airport elevation and weather conditions. Calculations by the FAA inspector estimated a minimum takeoff roll of 425 feet before rotation under ideal conditions for weather and mixture setting.

A witness reported the pilot was "hot dogging" and was trying to show off when the pilot took off in a very short distance and climbed at a steep angle. The witness reported that the airplane aerodynamically stalled, collided with trees and came to rest in a ditch. The witness also reported that the winds were calm at the time of the takeoff and accident.

The airplane came to rest on private property that abutted the airport, and the witness reported that the landowner dragged the airplane onto airport property with a tractor. The airplane wreckage was not photographed by the FAA inspector before it was moved.

Eight other airplanes of similar make and model departed the field about the time of the accident without incident.

The pilot reported no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

Frequently asked questions

How do I search flights by aircraft type on FlightFinder?

Pick an aircraft model — Boeing 737, Airbus A320, A380, Boeing 787 Dreamliner and more — enter your origin airport, and FlightFinder shows every route that plane flies from there with live fares.

Which aircraft types can I filter by?

We support Boeing 737/747/757/767/777/787, the full Airbus A220/A319/A320/A321/A330/A340/A350/A380 family, Embraer E170/E175/E190/E195, Bombardier CRJ and Dash 8, and the ATR 42/72 turboprops.

Is FlightFinder free to use?

Search and schedules are free. Pro ($4.99/month, $39/year, or $99 one-time lifetime) unlocks the enriched flight card — on-time stats, CO₂ per passenger, amenities, live gate & weather — plus My Trips with push alerts.

Where does the route data come from?

Live schedules come from Amadeus, AeroDataBox and Travelpayouts. Observed routes (which aircraft actually flew a given city pair) are crowdsourced from adsb.lol ADS-B data under the Open Database License.
