AD NUMBER: PL2005-05-53
MANUFACTURER: Cessna
SUBJECT: Airworthiness Directive PL2005-05-53
SUMMARY: The FAA has been notified that inadequate or incorrect flight controls rigging may exist on recently produced Cessna Models 172R, 172S, 182T, and T182T airplanes. The following issues were identified through Cessna's inspection of airplanes still at their production facility: - Two airplanes with ailerons not engaging the upper stops and one with a flap push/pull rod missing the nut on the bolt. - Elevator cables chafing fuel lines near the fuel selector, which caused damage to the fuel lines. - Elevator trim cables routed outside the cotter pins in the horizontal stabilizer. - Elevator trim cables crossed twice (trim functioned correctly in flight). - Control cables rubbing structures such as bulkheads and center consoles. - Aileron bell crank adjustment screw interference with stringer. - Barrels on control cables not safety pinned or incorrectly pinned. - Control cables routed outside of pulleys. - A bent flap bell crank. 

After careful review of all available information related to the subject presented above, FAA has determined that: - Operation of the affected Models 172R, 172S, 182T, and T182T airplanes should be prohibited until all the flight control systems are inspected and any discrepancies corrected; and  - AD action should be taken to prevent loss of airplane control due to incorrect or inadequate rigging of critical flight systems.
