This Continuing Airworthiness Notice (CAN) is issued to bring attention to two defect reports submitted to the CAA for Cessna 208B aircraft. The first report is about finding severely corroded and cracked elevator torque tubes on a Cessna 208B, and the second report is about finding a corroded rudder torque tube assembly on another Cessna 208B aircraft.

The purpose of this Continuing Airworthiness Notice (CAN) is to alert operators and maintainers of the importance of accomplishing a thorough inspection of the flap supports and rollers bearings for wear and corrosion. Service experience indicates the possibility of flap support wear by the flap roller bearings. Failure to accomplish a thorough inspection of the flap supports and roller bearings could result in damage to the flap supports, restriction of flap free movement, and a possible flap asymmetric condition.
