Cessna Aircraft Company Airplanes
(1) This AD applies to the following Cessna Aircraft Company (previously COLUMBIA or LANCAIR) Models LC40-550FG, LC41-550FG, and LC42-550FG airplanes that are certificated in any category:
(i) LC40-550FG (Model 300), serial numbers 40001 through 40079;
(ii) LC41-550FG (Model 400), serial numbers 41001 through 41108, 41501 through 41533, 41563 through 41800, and 411001 through 411161; and
(iii) LC42-550FG (Model 350), serial numbers 42001 through 42084, 42501 through 42569, and 421001 through 421020.
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.
(1) Within the next 50 hours time-in-service (TIS) after July 26, 2013 (the effective date of this AD) or within the next 3 months after July 26, 2013 (the effective date of this AD), whichever occurs first, incorporate figure 1 of paragraph (g)(1) of this AD into the applicable Pilot's Operating Handbook (POH)/FAA-approved Airplane Flight Manual (AFM), Section 2, Limitations (Other Limitations). This may also be done by inserting a copy of this AD into the POH/AFM.
(2) Within the next 50 hours TIS after July 26, 2013 (the effective date of this AD) or within the next 3 months after July 26, 2013 (the effective date of this AD), whichever occurs first, insert a copy of this AD into the POH/AFM or incorporate figure 2 of paragraph (g)(2) of this AD into the applicable POH/AFM at the end of each of the following sections:
