H I S T O R Y O F P R E V I O U S R E V I S I O N S Refer to the previous issues of AOT 27A3102. - The AOT 27A3102 was issued on May 30/02 to inform the operators about a repetitive inspection to be performed on the ball screw assy for integrity of the primary and secondary load path. - The AOT 27A3102 was revised on Jul 25/02 to provide operators with a simpler Inspection procedure and clearer GO/NOGO criteria. Revision No. 02 was issued to supersede AOT 27A3102 Rev. 01 (dated Jul 25/02). Revision No. 03 was issued to extend the effectivity and to amend worksteps in the para. preparation. Revision No. 04 was issued to correct the AMM reference, to add the inspection procedure for RH THS/THSA lower attachment and to change the inspection procedure from THS/THSA lower attachment to LH THSA. Revision No. 05 was issued to : - extend the effectivity to all A330-200 until MSN 0650 and A330-300 until MSN 0648. Revision No. 06 was issued to : - extend the effectivity up to aircraft MSN 0758, - update the preparation para. Revision No. 07 was issued to update the Effectivity.

O RY M A N DA TO RY M A N DA TO RY **ATA SYSTEM : 27 TITLE : FLIGHT CONTROLS - THSA - INSPECTION OF THE BALL SCREW ASSY FOR INTEGRITY OF**  **THE PRIMARY AND SECONDARY LOAD PATH MODIFICATION No. :**  INSPECTION R E A S O N /D E S C R I PT I O N /O P E RA T I O N A L C O N S E Q U E N C E S The THSA (Trimmable Horizontal Stabilizer Actuator) comprises a ball nut, which forms the primary load path and a threaded nut as a secondary load path. Both run on the screw shaft. In case of failure of the primary load path, loads are transferred to the secondary one. When the secondary nut is loaded, the friction increases between the titanium nut and steel screw due to material characteristics. Investigations of the THSA transfer tube have indicated that the THSA secondary nut does not lock the THSA after few movements as expected under certain cyclic load conditions but continues to operate with high friction which results in damage to the screw and the secondary nut. Operation of the secondary load path is detected by the Flight Control Primary Computers (FCPC) if the THSA efficiency decreases to such an extent that the position error monitoring threshold is exceeded. If this condition remains undetected, a primary load path failure may result in damage to the screw and secondary nut and, in extreme cases, in failure of the actuator. Accomplishment of this Service Bulletin is mandatory as per the latest issue of Consigne de Navigabilite (CN) (Airworthiness Directive (AD)) No. F-2002-414(B). This Service Bulletin is not applicable for aircraft with the CSP-System electrical connected to the FCPCs. It means that this Service Bulletin is not applicable for aircraft having accomplished Service Bulletin No. A330-92-3046 and Service Bulletin No. A330-27-3137 (for THSA PN 47172-XXX). This Service Bulletin which replaces AOT 27A3102 Rev. 01 (dated Jul 25/02) introduces a repetitive detailed visual inspection of the THSA ball screw assy and a check of the gap between the secondary tenons and the transfer plates with a feeler gage. The THSA must be replaced before next flight if cracks, distortion, dents or corrosion are found on the screw shaft, gimbal, fail safe plates, transfer plates, ball nut body, return tubes or collar, or if the feeler gage has failed at any 4 gaps. The inspection detailed in this Service Bulletin has to be repeated at intervals not exceeding 700 FH. The accomplishment of this Service Bulletin will ensure the reliable function of the THSA.

R E** **A S**  **O N**  (1) History The THSA (Trimmable Horizontal Stabilizer Actuator) comprises a ball nut, which forms the primary load path and a threaded nut as a secondary load path. Both run on the screw shaft. In case of failure of the primary load path, loads are transferred to the secondary one. When the secondary nut is loaded, the friction increases between the titanium nut and steel screw due to material characteristics. Investigations of the THSA transfer tube have indicated that the THSA secondary nut does not lock the THSA after few movements as expected under certain cyclic load conditions but continues to operate with high friction which results in damage to the screw and the secondary nut. Operation of the secondary load path is detected by the Flight Control Primary Computers (FCPC) if the THSA efficiency decreases to such an extent that the position error monitoring threshold is exceeded. If this condition remains undetected, a primary load path failure may result in damage to the screw and secondary nut and, in extreme cases, in failure of the actuator. Accomplishment of this Service Bulletin is mandatory as per the latest issue of Consigne de Navigabilite (CN) (Airworthiness Directive (AD)) No. F-2002-414(B). This Service Bulletin is not applicable for aircraft with the CSP-System electrical connected to the FCPCs. It means that this Service Bulletin is not applicable for aircraft having accomplished Service Bulletin No. A330-92-3046 and Service Bulletin No. A330-27-3137 (for THSA PN 47172-XXX). (2) Objective/Action This Service Bulletin which replaces AOT 27A3102 Rev. 01 (dated Jul 25/02) introduces a repetitive detailed visual inspection of the THSA ball screw assy and a check of the gap between the secondary tenons and the transfer plates with a feeler gage. The THSA must be replaced before next flight if cracks, distortion, dents or corrosion are found on the screw shaft, gimbal, fail safe plates, transfer plates, ball nut body, return tubes or collar, or if the feeler gage has failed at any 4 gaps. The inspection detailed in this Service Bulletin has to be repeated at intervals not exceeding 700 FH. (3) Advantages The accomplishment of this Service Bulletin will ensure the reliable function of the THSA. (4) Operational/Maintenance Consequences None **D.
