What to do
Owners and operators of Cessna 180, 182, and 185 series aircraft listed in the bulletin should incorporate the new inspection for excessive free play in the horizontal stabilizer trim actuator as outlined in the temporary maintenance manual revisions. This inspection is recommended every 1,000 flight hours to identify and address wear before it leads to trim freeze-up. For further information, contact the EASA Airworthiness Directives, Safety and Research Section.
Summary
FAA Special Airworthiness Information Bulletin CE-08-02 is an informational bulletin addressing an airworthiness concern affecting Cessna 180, 182, and 185 series aircraft. The bulletin highlights issues with horizontal stabilizer trim freeze-up in flight caused by excessive wear in the pitch trim actuator screw-jack threads, specifically involving parts with Cessna part numbers 0712500-13 and 0712500-11. This condition may impair pitch trim control and aircraft handling.
What changed
The bulletin introduces a recommendation for a new scheduled inspection of the horizontal stabilizer trim actuator free play to detect excessive wear. Cessna has issued temporary revisions to maintenance manuals for affected models and serial numbers to include this inspection every 1,000 flight hours. No mandatory airworthiness directive has been issued, and the bulletin serves as an advisory for operators and maintenance personnel.
Why it matters
This information is critical for operators, maintenance organizations, and compliance teams to prevent potential in-flight pitch trim control failures due to worn actuator components. Early detection through the recommended inspection can avoid unsafe flight conditions and costly repairs. Understanding this concern helps maintain aircraft safety and operational reliability for the affected Cessna models.
