### TITLE: FLIGHT CONTROLS - TRIMMABLE HORIZONTAL STABILIZER (THS) - IMPROVE THS UPPER ATTACHMENT **CONF ALL MODIFICATIONS MODIFICATION CLASSIFICATION MAJOR None MINOR 13427S22777 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 A specific failure case of the Trimmable Horizontal Stabilizer Actuator (THSA) upper primary attachment, which may result in a loading of the upper secondary attachment, has been identified by analysis. Primary load path failure can be caused by bearing migration from the upper attachment gimbal by failure or loss of a retention bolt. When engaged the secondary attachment will only withstand the loads for a limited period of time. This Service Bulletin is issued to advise all operators of A310 aircraft of the issue of GOODRICH Service Bulletin FLIGHT CONTROL - HORIZONTAL STABILIZER ACTUATOR (HSA) UPPER ATTACHMENT RETAINING PLATES. This Service Bulletin details installation of three secondary retention plates for the gimbal bearings on the THSA upper primary attachment. Accomplishment of this Service Bulletin will prevent upper attachment bearing migration and subsequent primary load path failure.

D. DESCRIPTION To accomplish this Service Bulletin it is necessary to : **CONF 001 Task 272103-831-801-001: Modification of the THSA Upper Attachment. (1) Install retaining plates on the THSA upper attachment. **CONF 002 Task 272103-831-801-001: Modification of the THSA Upper Attachment. (1) Install retaining plates on the THSA upper attachment. **CONF ALL E. COMPLIANCE (1) Classification MANDATORY: Service Bulletin must be accomplished. (2) Accomplishment Timescale Accomplishment of this Service Bulletin is requested within 30 months from original issue date of the SB. Accomplishment of this Service Bulletin is expected to be rendered mandatory by the issue of an Airworthiness Directive (AD) published by the European Aviation Safety Agency (EASA). 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. F. APPROVAL Approved under EASA Design Organisation Approval No. EASA 21J.031. If an aircraft listed in the effectivity has a modification or repair embodied that is not of AIRBUS origin, and which affects the content of this Service Bulletin, the operator is responsible for obtaining approval by its airworthiness authority for any adaptation necessary before incorporation of the Service Bulletin. G. MANPOWER The manpower estimates given in this Service Bulletin are based on the direct labor cost to do the work. These estimates assume that the work will be done by experienced personnel, and may need to be revised upwards to suit operator’s circumstances.
