AD NUMBER: 2006-26-10
MANUFACTURER: Airbus
SUBJECT: Airworthiness Directive 2006-26-10
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A300 B2 and B4 series airplanes. This AD requires revising the airplane flight manual (AFM) to include procedures for resetting the trim and pitch trim levers after each landing, determining which servo motor moves the pitch trim control wheel, and doing applicable other specified actions. This AD also provides for optional terminating actions for those requirements. This AD results from a report of a sudden nose-up movement after disengagement of the autopilot in cruise. We are issuing this AD to ensure that the flightcrew is aware of the procedures for resetting the trim and pitch trim levers after each landing and to prevent failure of the servo motors of the pitch trim systems during flight. Failure of the servo motors of the pitch trim systems could result in uncommanded nose-up movement of the control surface of the pitch trim systems after disengagement of the autopilot in cruise.
