REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

The aim of the AMM Task 27-44-51-220-801 is to perform the integrity check of the Trimmable

Horizontal Stabilizer Actuator (THSA) ballscrew shaft (Primary and Secondary Load path).

Current AMM Task 27-44-51-220-801 checks the ballscrew shaft integrity by applying a differential

torque between the ballscrew (Primary Load path) and the tie bar (Secondary Load path).

This check is satisfactorily passed if there is a limited differential rotation between the primary and the

secondary load paths.

AMM Task 27-44-51-220-801 is called by the MRB task 274000-12 every 16,000FH.

Further to corrosion issue identified in service on THSA PN 47147-500 and 47147-700 at the level of

the ballscrew lower splines (which are loaded only in case of ballscrew rupture), an interval reduction of

the ballscrew integrity check is proposed as a protective action.

This Inspection Service Bulletin requires the application of the Ballscrew Integrity Check as per MRB

task 274000-12 on THSA PN 47147-500 and 47147-700 every 12,000 FH / 4,400 FC.

Accomplishment of this Service Bulletin will permit to ensure a reliable function of the THSA by

checking the ballscrew integrity.

SERVICE BULLETIN

C. REASON

(1) History

The aim of the AMM Task 27-44-51-220-801 is to perform the integrity check of the

Trimmable Horizontal Stabilizer Actuator (THSA) ballscrew shaft (Primary and Secondary

Load path).

Current AMM Task 27-44-51-220-801 checks the ballscrew shaft integrity by applying a

differential torque between the ballscrew (Primary Load path) and the tie bar (Secondary

Load path).

This check is satisfactorily passed if there is a limited differential rotation between the

primary and the secondary load paths.

AMM Task 27-44-51-220-801 is called by the MRB task 274000-12 every 16,000FH.

Further to corrosion issue identified in service on THSA PN 47147-500 and 47147-700

at the level of the ballscrew lower splines (which are loaded only in case of ballscrew

rupture), an interval reduction of the ballscrew integrity check is proposed as a protective

action.

(2) Objective/Action

This Inspection Service Bulletin requires the application of the Ballscrew Integrity Check

as per MRB task 274000-12 on THSA PN 47147-500 and 47147-700 every 12,000 FH /

4,400 FC.

(3) Advantages

Accomplishment of this Service Bulletin will permit to ensure a reliable function of the

THSA by checking the ballscrew integrity.

(4) Operational/Maintenance Consequences

None

D. DESCRIPTION

To accomplish this Service Bulletin it is necessary to :

Task 273191-832-801-001: Inspection

(1) Do a Special Detailed Inspection of the THSA Ballscrew

(2) Replace the Trimmable Horizontal Stabilizer Actuator (THSA)

F. APPROVAL

The technical content of this document is approved under the authority of 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. The estimates do not

include the time to prepare, plan or inspect the work. Manufacture and procurement of parts

and tools, drying times for paints, sealants, etc., and general administration work are also not

included.
