On March 6, 1983, a North American AT-6 (registration N9786Z) was involved in an aviation accident near Norman, OK. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During a crosswind landing, an aircraft swerved after touchdown, struck a sawhorse marking the runway edge, and then hit another sawhorse marking deteriorating asphalt. No mechanical malfunction was found.
Landing and Initial Swerve
During arrival, the pilot landed with a 30-degree left crosswind. The aircraft touched down in a three-point attitude. After touching down, the aircraft swerved to the right and turned approximately 25 degrees before the pilot regained control.
Collision with Sawhorses
The pilot then corrected the heading to parallel the runway. At that point, the aircraft was positioned approximately 10 feet to the right of a white line marking the edge of the maintained runway. The aircraft then struck a sawhorse surface. As the pilot initiated a turn back toward the open portion of the runway, the aircraft struck another sawhorse marking an area of deteriorating asphalt.
Aircraft Examination
No mechanical malfunction was found that would have caused the loss of control.
