Compliance: Required within the next 50 hours time-in-service (TIS) after the effective date of this AD, unless already accomplished.

To prevent failure of the Part Number (P/N) 2622083-18 bellcrank assembly and the resulting unexpected retraction of the flaps, accomplish the following:

  (a) Visually inspect the P/N 2622083-18 bellcrank assembly for cracks, deformation, and incomplete welds in accordance with Cessna Service Bulletin CAB89-34, dated December 22, 1989.

  (1) If any cracks or deformation are found, prior to further flight replace the P/N 2622083-18 bellcrank with an airworthy bellcrank.

  (2) If any incomplete welds are found, within the next 50 hours TIS replace the P/N 2622083-18 bellcrank with an airworthy bellcrank.

  (3) If any bellcranks are to be replaced, inspect the replacement part in accordance with Cessna SB CAB89-34 dated December 22, 1989 before installation.

  (b) Airplanes may be flown in accordance with FAR 21.197 to a location where this AD may be accomplished.

  (c) An alternate method of compliance or adjustment of the initial or repetitive compliance times which provides an equivalent level of safety may be approved by the Manager, Wichita Aircraft Certification Office, 1801 Airport Road, Room 100, Wichita, Kansas 67209.

NOTE: The request should be forwarded through an FAA Maintenance Inspector, who may add comments and then send it to the Manager, Wichita Aircraft Certification Office.

Box 7704, Wichita, Kansas 67217, or may examine this document at the FAA, Central Region, Office of the Assistant Chief Counsel, Room 1558, 601 East 12th Street, Kansas City, Missouri 64106.
