To prevent failure of the throttle control bellcrank and the throttle and mixture support shaft, unless already accomplished, perform the following:

  (1) Within 10 hours' time in service after the effective date of this AD, visually inspect the throttle control bellcrank P/N 0750163-1 for cracks or broken welds around the welded center boss. If cracks or a broken weld is found, replace the bellcrank with a strengthened Cessna P/N 0750163-4 in accordance with Cessna Service Letter SE68-28, Supplement No. 1, or an equivalent modification approved by the Chief, Engineering and Manufacturing Branch, FAA, Central Region. If this strengthened part P/N 0750163-4 is not available, P/N 0750163-1 may be installed. The aircraft may then be operated not to exceed 100 hours at which time P/N 0750163-4 must be installed prior to further flight.

  (2) If any cracks are found during the inspection required by Paragraph (1), a description of such cracks and the time in service as of the date of said inspection should be reported to the local General Aviation District Office on FAA Form FAA-1226. (Reporting approved by the Bureau of the Budget under BOB No. 04-R0174.)
