3/10 complexity

This Directive requires modification of the three rudder servo‑controls on specified Airbus A330 models, following Airbus Service Bulletin A330‑27‑3101. It affects operators/owners of A330‑201/202/203/223/243 aircraft (unless Airbus Mod 48510 or that service bulletin is already fitted) and must be done before 30 June 2005 to prevent a rudder‑servo failure that could, with an engine failure, create a critical situation.

AD/A330/16 Rudder Servo-Controls 5/2003

Applicability: All Model A330-201, -202, -203, -223, and -243 aircraft; except for aircraft with Airbus Modification 48510 incorporated in production, or Airbus Service Bulletin A330-27-3101 incorporated in service.

Requirement: Modify the three rudder servo-controls in accordance with Airbus Service Bulletin A330-27-3101.

Note: DGAC AD 2003-102(B) refers.

Compliance: Before 30 June 2005, unless already accomplished.

This Airworthiness Directive becomes effective on 15 May 2003.

Background: During a pre- flight check on a Model A330-200 aircraft, the message “F/CTL RUD Y SERVO JAM” was displayed. Two further occurrences have been reported on other aircraft. Investigation revealed the driving finger of the affected rudder servo-control had failed due to fatigue, with consequent loss of the rudder servo-control. If not corrected, loss of the rudder servo-control, combined with an engine failure at take- off or during go-around, could lead to a potentially critical situation.
