All other changes are major changes. REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES First delivered aircraft were equipped with Trimmable Horizontal Stabilizer Actuator (THSA) 47147 family which are no longer produced. THSA 47172 family is the current production standard. This Service Bulletin covers the introduction of THSA PN 47172-530 in replacement of THSA PN 47147-700. Accomplishment of this Service Bulletin allows: - Aircraft configuration evolution towards the current THSA family production standard, - Anticipation on obsolescence of THSA 47147 family, - Resolution of in-service issues encountered with THSA 47147 family (Technical Follow Up (TFU) 27.44.51.010).
