### TITLE: FLIGHT CONTROLS - TRIMMABLE HORIZONTAL STABILIZERS (THS) - BALLSCREW LOWER SPLINES CORROSION INSPECTION **CONF ALL
MODIFICATIONS
None REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES Some Trimmable Horizontal Stabilizer Actuators (THSA) P/N 47145-XXX have been found with corrosion affecting the ball screw lower splines. The root cause of corrosion of splines is the result of the removal of the Molykote protection due to friction combined with the ingress of the water due to condensation associated to temperature cycling between ground and high altitude. This Inspection Service Bulletin requires an inspection on ball screws on all THSA P/N 47145- XXX older than 20 years since new. This Service Bulletin is published to advise operators of A318/A319/A320/A321 aircraft of the issue of the Goodrich Actuation Systems Service Bulletin N ̊ 47145-27-16 which defines the acceptable corrosion on the lower splines on the THSA screw shaft. Accomplishment of this Service Bulletin will permit to detect corrosion and ensure the reliable function of the THSA.

SERVICE BULLETIN

C. REASON (1) History Some Trimmable Horizontal Stabilizer Actuators (THSA) P/N 47145-XXX have been found with corrosion affecting the ball screw lower splines. The root cause of corrosion of splines is the result of the removal of the Molykote protection due to friction combined with the ingress of the water due to condensation associated to temperature cycling between ground and high altitude. (2) Objective/Action This Inspection Service Bulletin requires an inspection on ball screws on all THSA P/N 47145-XXX older than 20 years since new. This Service Bulletin is published to advise operators of A318/A319/A320/A321 aircraft of the issue of the Goodrich Actuation Systems Service Bulletin N ̊ 47145-27-16 which defines the acceptable corrosion on the lower splines on the THSA screw shaft. (3) Advantages Accomplishment of this Service Bulletin will permit to detect corrosion and ensure the reliable function of the THSA. (4) Operational/Maintenance Consequences
None
D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : Task 271214-832-801-001: Inspection (1) Do a Detailed Inspection of the THSA Ball screw Task 271214-833-801-001: Repair (1) Replace the Trimmable Horizontal Stabilizer Actuator (THSA) (if applicable)
E. COMPLIANCE (1) Classification RECOMMENDED: Service Bulletin recommended to be accomplished to prevent significant operational disruptions. (2) Accomplishment Timescale This Service Bulletin has been classified Recommended. It is expected that an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA) will be issued to change this classification to Mandatory. It is anticipated that the AD will confirm the (thresholds and/or intervals and/or date) given above but reference should be made to the AD for confirmation of the mandated accomplishment timescale.
