During takeoff with a strong quartering tailwind, an airplane veered left. The pilot could not correct with rudder, and the aircraft departed the airstrip, contacting a levee and losing main gear.

Incident Overview

A pilot reported that during takeoff, the airplane experienced an unexpected veer to the left, which he was unable to counteract using rudder inputs. The incident occurred at an airstrip where the local wind conditions were from 315 degrees at 15 to 20 knots. According to the pilot, the takeoff was initiated with a strong quartering tailwind.

Sequence of Events

The airplane traveled off the left side of the airstrip and into an adjacent rice field. While traversing the field, the aircraft struck a levee, resulting in the separation of the main landing gear. The pilot noted that he had begun flying at 0700 central daylight time and had completed 24 loads prior to the accident flight.

Pilot Statement

The pilot stated that the airplane veered left during the takeoff roll and that rudder application was insufficient to correct the deviation. He attributed the veer to the quartering tailwind conditions present at the time of takeoff.

Aircraft and Operational Details

The specific aircraft type, registration, and engine count are not available from the source. No information was provided regarding occupants, injuries, or damage to other components. The time of day was early morning, with the pilot having commenced operations at 0700 CDT. The source does not include any assessment of weather conditions beyond the wind direction and speed, nor does it mention air traffic control involvement.

Conclusion

The event involved a takeoff with a quartering tailwind, leading to a loss of directional control and a subsequent excursion from the runway surface. The main landing gear was damaged upon contact with a levee. No probable cause has been stated in the source material.
