## Summary

We propose to revise Airworthiness Directive (AD) 2007-07-06, which applies to certain Cessna Aircraft Company (type certificate previously held by Columbia Aircraft Manufacturing) (Cessna) Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes. AD 2007-07-06 currently requires the following: adding information to the limitations section of the airplane flight manual (AFM); repetitively inspecting the aileron and the elevator linear bearings and control rods for foreign object debris, scarring, or damage; and taking all necessary corrective actions. Since we issued AD 2007-07-06, Cessna has issued a new service bulletin that contains procedures for installing an access panel to facilitate the required inspections. Consequently, this proposed AD would retain the actions currently required in AD 2007-07- 06; allow installing access panels; and change the serial number applicability. We are proposing this AD to prevent jamming in the aileron and elevator control systems, which could result in failure. This failure could lead to loss of control.
