AIR TRACTOR INC AT-502BS/N: 502B-0315

Summary

On July 10, 2009, a Air Tractor INC AT-502B (N60023) was involved in an incident near Reydell, AR. All 1 person aboard were uninjured. The aircraft sustained substantial damage.

The National Transportation Safety Board determined the probable cause of this incident to be: The pilot's inability to maintain control of the airplane when it unexpectedly encountered a whirlwind shortly after takeoff.

The pilot took off from a private strip on an aerial application flight. While climbing away from the runway the airplane began a left turning tendency. The pilot suspected the airplane encountered a whirlwind and attempted to maintain control of the airplane. When the airplane entered a "dead air space" the airplane was approximately 5 to 10 feet above the ground. The airplane subsequently collided with terrain and came to a stop in the upright position. Substantial damage was sustained to both wings. An inspection of the airplane by a Federal Aviation Administration inspector did not reveal any pre-impact anomalies.

This incident is documented in NTSB report CEN09CA428. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N60023.
