Applicability: Models 411 and 411A airplanes (all serial numbers), certificated in any category.
Compliance: Required within the next 30 calendar days after the effective date of this AD, unless already accomplished.
To ensure that the correct takeoff performance information is available to the pilot, accomplish the following:
(a) Using pen and ink, modify the Airplane Flight Manual and Owner's Manual as follows:
NOTE 1: It is recommended that any locally developed pilot's checklists be modified in accordance with the following paragraphs.
(1) Change the liftoff (rotation) airspeed to 108 miles per hour indicated airspeed (MPH IAS) for all weights.
(2) Change the speed used upon reaching a height of 50 feet above the takeoff surface to 114 MPH IAS for all weights.
(3) Increase all listed takeoff distances by 500 feet to account for the higher takeoff airspeeds.
(4) If the Owner's Manual contains charts identified as "Normal Takeoff Distances", "Single Engine Takeoff Performance" or "Accelerate Stop Distance", mark each chart with large letters stating "DO NOT USE".
NOTE 2: Cessna has published a booklet entitled "Pilot Safety and Warning Supplements", dated October 2, 1985, that provides material related to the subject matter of this AD, specifically the subjects "Single Engine Flight Information" and "Aircraft Loading".
(b) FAR 43.3 notwithstanding, the actions required by this AD may be performed by a pilot and must be recorded in accordance with FAR Section 43.9.
(c) An alternate method of compliance or adjustment of the compliance time that provides an equivalent level of safety may be approved by the Manager, Wichita Aircraft Certification Office, 1801 Airport Road, Room 100, Mid-Continent Airport, Wichita, Kansas 67209; Telephone (316) 946-4400.
