HISTORY OF FLIGHT On June 3, 1993, at 1029 eastern daylight time, a Corben Jr, Ace, N17BA, registered to and piloted by Mr. Brian Amato was substantially damaged when it swerved to the left during its landing roll on runway 36 (5108' X 150' dry asphalt) at the Traverse City, Cherry Capital City Airport, Traverse City, Michigan. Visual meteorological conditions prevailed at the time of the accident and a flight plan had not been filed for the 14 CFR Part 91 flight. The pilot, the sole occupant was not injured. The pilot stated that once all three wheels were on the ground, the airplane made a slight veer to the left which he attempted to correct with right rudder. There was no response from the right rudder pedal and the aircraft continued to turn left entering what he describes as a classic ground loop, dropping the right wing to the pavement. PERSONNEL INFORMATION The pilot possess a commercial pilot certificate, with an airplane single-engine land, private pilot rating, issued on October 31,1991. His second class medical certificate without restrictions was issued on August 30, 1991. AIRCRAFT INFORMATION The airplane was a Brian Amato, Corben Junior Ace, an experimental home built, constructed by the registered owner. WRECKAGE AND IMPACT INFORMATION On scene investigation revealed that the right main landing gear had collapsed, to the left, under the fuselage. The wooden propeller was destroyed and damage to the right main wing spar and some wing ribs was incurred. TEST AND RESEARCH Post event inspection of the Scott tailwheel revealed a lack of lubrication and seized wheel bearings. Testing indicated that the dragging tail wheel could cause the wheel to be pulled from its spring loaded indent causing a loss of rudder pedal/ tail wheel control.
