Aircraft Accident/Incident Report

Easton, Pennsylvania 18042
Saturday, June 7, 1997 9:15 EDT

NTSB Narrative Summary Released at Completion of Accident

After departure and level off, the pilot performed a shallow left turn. When he tried to level the wings, he found he had lost aileron control. By use of the rudder and power, he performed a forced landing into a field and struck trees. Post accident investigation revealed the accident flight was the first flight following an annual inspection, and that a pulley in the aileron system, located on a wing strut, was chipped, and that the aileron cable had come out of its track, and tension was lost in the aileron system.

NTSB Probable Cause Narrative

A failed aileron pulley which resulted in loss of tension and subsequent loss of aileron control. A factor was the failure of the mechanic to detect the failed aileron pulley during the annual inspection.
