Compliance: Required as indicated, unless already accomplished.

A. Before the next flight of the affected airplanes, visually inspect the P/N C301002-0101 (12 volt) or C301002-0102 (24 volt) wing flap actuator for the date code stamp.

1. If the date code stamp on the actuator is OH, HH, WH, or ZH install a placard near the flap control which reads: "FLAP EXTENSION PROHIBITED" and operate the aircraft in accordance with this limitation.

2. Within 50 hours' time in service after the effective date of this AD, replace the wing flap actuator ball nut assembly with an airworthy assembly in accordance with Cessna Service Letter SE76-25, dated December 13, 1976, or later approved revision. The placard required by Paragraph A.1. may be removed when the replacement ball nut assembly is installed.

3. If the date stamp code on the actuator is not one of those identified in Paragraph A.1., make an entry in the aircraft maintenance records indicating that this AD has been accomplished and the airplane may be returned to service.

B. Airplanes located where the inspection cannot be accomplished may be flown in accordance with FAR 21.197 to a place where the inspection may be accomplished, providing the flaps are not used for the flight.

C. Any equivalent method of compliance with this AD must be approved by the Chief, Engineering and Manufacturing Branch, FAA, Central Region.

NOTE 1. The date code stamp is steel stamped into the lower side of the actuator gear housing, adjacent to the flap motor and switch bar, is visible on the lower side of the actuator as it is installed in the aircraft. Inked stamped numbers on the motor housing are to be disregarded.

NOTE 2. The manufacturer has advised the FAA that sufficient replacement parts are available to accomplish Paragraph A.2. of this AD.

This amendment becomes effective February 3, 1977, to all persons except those to whom it was made effective earlier by air mail letters dated January 13, 1977.
