For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CASR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.

AD/A330/29 'SAMM' Elevator Servo-control 4/2004

Applicability: AIRBUS INDUSTRIE A330 aircraft, models -202, -223, -243, -301, -321, -322, -323,

-341, -342, and -343, all serial numbers, fitted with “SAMM” elevator servo-control with Part Number (P/N) SC4800-2 through SC4800-7 and SC4800-8 except those aircraft which have received in production AIRBUS INDUSTRIE modification 47674 or in service AIRBUS INDUSTRIE Service Bulletin (SB) A330-27-3076 R2 or earlier revisions.

Requirement:  1. Check the play of the piston rod eye-end of the active and damping servo- controls (FIN 2CS1, 2CS2, 3CS1 and 3CS2) in accordance with paragraph 3.B.(2) of Airbus SB A330-27-3062R4 or earlier revisions.

2.         Depending on the play measured for each servo-control, perform the corrective action as detailed in Airbus SB A330-27-3062 R4 or earlier revisions.

3.         Replace all servo-controls P/N SC4800-2 through SC4800-7 and SC4800-8 with servo-controls P/N SC4800-7A or SC4800-9 in accordance with Airbus SB A330-27-3076 R2 or earlier revisions.

Note 1: DGAC AD 2001-518(B) refers.

Note 2: Fitment of P/N SC4800-7A or -9 servo-controls provides terminating action to this Directive.

Compliance: For Requirements 1 and 2: Unless already accomplished, initial inspection before the accumulation of 30 months servo-control time in service since new, or within 100 flight hours from the effective date of this Directive, whichever occurs later, thereafter at intervals not to exceed 15 months from the previous inspection.

For Requirement 3: Not later than 31 August 2004.

This Airworthiness Directive becomes effective on 15 April 2004.

AD/A330/29 (continued)

Background: Rupture of the active elevator servo-control piston rod due to degradation of the lubricating liner from the eye end spherical bearing can lead to loss of damping and subsequent loss control of the elevator. This Directive addresses the unsafe condition by repetitive inspection and eventual replacement of the servo-control with a servo- control that has better retention of the lubricating liner.
