### TITLE: FLIGHT CONTROLS - TRIMMABLE HORIZONTAL STABILIZER ACTUATOR - BALLSCREW INTEGRITY CHECK **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES The aim of the AMM Task 27-44-51-220-801 is to perform the integrity check of the Trimmable Horizontal Stabilizer Actuator (THSA) ballscrew shaft (Primary and Secondary Load path). Current AMM Task 27-44-51-220-801 checks the ballscrew shaft integrity by applying a differential torque between the ballscrew (Primary Load path) and the tie bar (Secondary Load path). This check is satisfactorily passed if there is a limited differential rotation between the primary and the secondary load paths. AMM Task 27-44-51-220-801 is called by the MRB task 274000-12 every 16,000FH. Further to corrosion issue identified in service on THSA PN 47147-500 and 47147-700 at the level of the ballscrew lower splines (which are loaded only in case of ballscrew rupture), an interval reduction of the ballscrew integrity check is proposed as a protective action. This Inspection Service Bulletin requires the application of the Ballscrew Integrity Check as per MRB task 274000-12 on THSA PN 47147-500 and 47147-700 every 12,000 FH / 4,400 FC. Accomplishment of this Service Bulletin will permit to ensure a reliable function of the THSA by checking the ballscrew integrity.

# @A330 SERVICE BULLETIN
C. REASON (1) History The aim of the AMM Task 27-44-51-220-801 is to perform the integrity check of the Trimmable Horizontal Stabilizer Actuator (THSA) ballscrew shaft (Primary and Secondary Load path). Current AMM Task 27-44-51-220-801 checks the ballscrew shaft integrity by applying a differential torque between the ballscrew (Primary Load path) and the tie bar (Secondary Load path). This check is satisfactorily passed if there is a limited differential rotation between the primary and the secondary load paths. AMM Task 27-44-51-220-801 is called by the MRB task 274000-12 every 16,000FH. Further to corrosion issue identified in service on THSA PN 47147-500 and 47147-700 at the level of the ballscrew lower splines (which are loaded only in case of ballscrew rupture), an interval reduction of the ballscrew integrity check is proposed as a protective action. (2) Objective/Action This Inspection Service Bulletin requires the application of the Ballscrew Integrity Check as per MRB task 274000-12 on THSA PN 47147-500 and 47147-700 every 12,000 FH / 4,400 FC. (3) Advantages Accomplishment of this Service Bulletin will permit to ensure a reliable function of the THSA by checking the ballscrew integrity. (4) Operational/Maintenance Consequences None D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : Task 273191-832-801-001: Inspection (1) Do a Special Detailed Inspection of the THSA Ballscrew (2) Replace the Trimmable Horizontal Stabilizer Actuator (THSA) E.
