Unsafe condition

This AD was prompted by a manufacturer safety analysis review on flight control which resulted in recommendations for reduced repetitive inspection intervals for the flight controls certification maintenance requirements (CMR) of the tab-to-actuator linkage. We are issuing this AD to prevent failure of these components or their constituent parts which could lead to reduced control of the airplane.

Affected ADs

None.
