### TITLE: FLIGHT CONTROLS - TRIMMABLE HORIZONTAL STABILIZER ACTUATOR - THSA SCREW SHAFT LOWER SPLINES INSPECTION (P/N 47147-500 AND -700) **CONF ALL MODIFICATIONS None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES Some Trimmable Horizontal Stabilizer Actuators (THSA) PN 47147-500 have been found with corrosion affecting the ballscrew lower splines (between the tie bar and the screwjack). Investigations have identified the root cause for the corrosion : - Contact/friction between the tie bar and the inner surface of the ballscrew leads to the removal of Molykote (corrosion protection) in front of the tie bar splines, - Humidity ingress initiates surface oxidation starting from surfaces where Molykote is removed, - Water retention in lower part leads to corrosion spread out and apparition of a brown deposit (iron oxide). This Inspection Service Bulletin requires an inspection of ballscrew lower splines on all THSA PN 47147-500 older than 11 years since retrofit -400 (or -400 new). This inspection impacts also the THSA PN 47147-700 as the introduction of the CSP does not change the material of the ballscrew. This Service Bulletin is published to advise operators of A330-300 aircraft of the issuance of Goodrich Actuation Systems Service Bulletin No. 47147-27-18 which defines the acceptable corrosion on the lower splines on the THSA screwjack. Accomplishment of this Service Bulletin permits to detect corrosion and contributes to ensure the reliable function of the THSA.

# @A330 SERVICE BULLETIN
C. REASON (1) History Some Trimmable Horizontal Stabilizer Actuators (THSA) PN 47147-500 have been found with corrosion affecting the ballscrew lower splines (between the tie bar and the screwjack). Investigations have identified the root cause for the corrosion : - Contact/friction between the tie bar and the inner surface of the ballscrew leads to the removal of Molykote (corrosion protection) in front of the tie bar splines, - Humidity ingress initiates surface oxidation starting from surfaces where Molykote is removed, - Water retention in lower part leads to corrosion spread out and apparition of a brown deposit (iron oxide). (2) Objective/Action This Inspection Service Bulletin requires an inspection of ballscrew lower splines on all THSA PN 47147-500 older than 11 years since retrofit -400 (or -400 new). This inspection impacts also the THSA PN 47147-700 as the introduction of the CSP does not change the material of the ballscrew. This Service Bulletin is published to advise operators of A330-300 aircraft of the issuance of Goodrich Actuation Systems Service Bulletin No. 47147-27-18 which defines the acceptable corrosion on the lower splines on the THSA screwjack. (3) Advantages Accomplishment of this Service Bulletin permits to detect corrosion and contributes to ensure the reliable function of the THSA. (4) Operational/Maintenance Consequences None D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : Task 273179-832-801-001: Inspection (1) Do a Detailed Inspection of the THSA Ballscrew Task 273179-833-801-001: Repair (1) Replace the Trimmable Horizontal Stabilizer Actuator (THSA)
