A factor was the collapse of the right main landing gear. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - recovery from bounced landing - inadequate, pilot in command (cause) - directional control - not maintained, pilot in command (cause) - ground loop/swerve - inadvertent, pilot in command - Main gear collapsed, landing - flare/touchdown - landing gear,main gear - overload (contributing factor) ## Analysis The pilot reported that the airplane bounced on landing. He reported that the airplane veered left on the second touchdown. The pilot reported that he was unable to regain directional control prior to the airplane traveling off the left side of the runway. The airplane then ground looped and the right main gear collapsed. ## Factual narrative On May 16, 2001, at 1315 central daylight time, an Air Tractor G-164A, N970X, was substantially damaged following a loss of control while landing on runway 31 (3,900 feet by 75 feet) at the Casselton Municipal Airport, Casselton, North Dakota.
