Aircraft Accident/Incident Report

Wheeling, Illinois 60090
Monday, April 26, 1999 9:30 CDT

NTSB Narrative Summary Released at Completion of Accident

During the run-up flight control checks prior to takeoff, the pilot experienced an aileron control failure. He was unable to obtain left aileron up movement. Inspection determined that the aileron had 4 degrees of up travel. Normal travel was 20 degrees +/- 2 degrees. Further inspection revealed that one of the aileron control bellcrank stop bolt/jam nut assemblies was loose allowing the stop bolt to rotate out of the threaded boss. This restricted the aileron movement. The three other stop bolt/jam nut assemblies were also inspected and were found to be loose. The airplane was a 1999 model, s/n 25, which had a total of approximately 11 hours on it at the time of the incident. In response to this incident Cessna Aircraft Company issued Special Service Project SSP99-27-02. On June 21, 1999, the Federal Aviation Administration issued Airworthiness Directive, 99-13-04, effective July 13, 1999. The AD requires '...inspecting the left and right wing aileron control bellcrank stop bolts and lock nuts for flush and tight contact with the surface of the threaded boss on each end of the yoke assemblies, and accomplishing follow-on and corrective actions, as applicable.'

NTSB Probable Cause Narrative

improper installation of the aileron control bellcrank stop bolts and lock nuts during the manufacturing process which resulted in a binding aileron control surface.
