This directive requires owners/operators of certain Cessna 150/152 models (unless modified per Cessna S.I. SE83-31) to visually inspect rudder pedal torque tubes at the welded spigot joints for cracks before the next Maintenance Release after 30 April 1984 and at each subsequent Maintenance Release. It targets a known failure that can cause loss of rudder and braking control, placing inspection costs and compliance on operators/maintenance organizations.
