AD/CESSNA 400/94 Aileron Hinge Assembly 7/88
Applicability: Cessna 404 with S/Nos 404-0001 to 404-0859 inclusive. Requirement: Modify in accordance with Cessna SB MEB 85-8 and SIL ME 83-25. Compliance: Not later than 31 December 1988.
Background: The original aileron hinge assembly design made it difficult to correctly install and secure the pivot bolt without overtorqueing. The resultant overstressing of the hinge brackets has led to their premature failure in a number of cases, and in one instance the aileron jammed in the wing structure, nearly causing loss of the aircraft. The manufacturer has redesigned the hinge assembly to help prevent further problems.
