NOTE: As per EASA IR 21, a minor change is one that has no appreciable effect on the

mass, balance, structural strength, reliability, operational characteristics affecting the

airworthiness of the product. 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).

Accomplishment of this Service Bulletin cancels the inspection requirements of Service Bulletin

27-4175.
