This Airworthiness Directive requires owners/operators of specified Mitsubishi MU-2 serial-numbered aeroplanes to have the flap flexible drive shaft sealed and its torque checked by following Mitsubishi Service Bulletin No. 198. Actions must be done at the next scheduled Maintenance Release after 31 December 1985. It affects aircraft operators and maintenance personnel, was issued because moisture ingress caused shaft failures, and imposes compliance costs (inspection, sealing, torque checks and any repairs) on the owner/operator.
