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.

C. REASON

(1) History

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.

(2) Objective/Action

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.

(3) Advantages

Accomplishment of this Service Bulletin will prevent upper attachment bearing migration

and subsequent primary load path failure.

SERVICE BULLETIN

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. 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.
