Full official abstract

This amendment adopts a new airworthiness directive (AD) that applies to Cessna Aircraft Company (Cessna) Model 172R airplanes equipped with a certain modification kit that reduces friction in the elevator control system. This AD requires inspecting the control yoke pivot bolt to assure positive clearance between the pivot bolt's threaded end and aileron direct cable. If positive clearance is not found, this AD requires replacing the control yoke pivot bolt, inspecting the adjacent aileron control cables for damage, and replacing any damaged aileron control cable. This AD is the result of the manufacturer supplying incorrect length control yoke pivot bolts in Cessna Modification Kits MK 172-27-01 that were shipped from September 21, 1998, through April 18, 1999. The actions specified by this AD are intended to prevent failure of an aileron control cable because of an incorrect length control yoke pivot bolt rubbing on one of these cables, which could result in loss of aileron control with loss of directional control of the airplane.
