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 P/N 47172-300 in replacement of THSA P/N 47147-500. Accomplishment of this Service Bulletin allows: - Aircraft configuration evolution towards the current THSA family production standard including the latest standards when associated with Service Bulletin 27-4136. - Anticipation on obsolescence of THSA 47147 family - Resolution of in-service issues encountered with THSA 47147 family (Technical Follow Up 27.44.51.010).
