Boeing Proposes Airworthiness Directive to Replace Elevator Tab Control Mechanisms on 737 Series Airplanes
Boeing is proposing to supersede an existing airworthiness directive for the 737-600, -700, -700C, -800, -900, and -900ER series airplanes, requiring the replacement of elevator tab control mechanisms with modified attach lugs to prevent severe vibration and structural failure.
