Airworthiness Directives; Cessna Aircraft Company Airplanes

We are adopting a new airworthiness directive (AD) for certain Cessna Aircraft Company (Cessna) (previously COLUMBIA or LANCAIR) Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes. This AD was prompted by reports that during maximum braking, if the brakes lock up and a skid occurs, a severe oscillatory yawing motion or "wheel walk" may develop, which could result in further significant structural damage to the airplane. This AD requires insertions into the pilot's operating handbook (POH) and the airplane maintenance manuals (AMM) regarding proper use of the brakes and inspection of the aft fuselage. We are issuing this AD to correct the unsafe condition on these products.
