REASON/DESCRIPTION/OPERATIONAL CONSEQUENCES

Some Trimmable Horizontal Stabilizer Actuators (THSA) PN 47147-500 have been found with corrosion

affecting the ballscrew lower splines (between the tie bar and the screwjack).

Investigations have identified the root cause for the corrosion :

- Contact/friction between the tie bar and the inner surface of the ballscrew leads to the removal of

Molykote (corrosion protection) in front of the tie bar splines,

- Humidity ingress initiates surface oxidation starting from surfaces where Molykote is removed,

- Water retention in lower part leads to corrosion spread out and apparition of a brown deposit (iron

oxide).

This Inspection Service Bulletin requires an inspection of ballscrew lower splines on all THSA PN

47147-500 older than 11 years since retrofit -400 (or -400 new).

This inspection impacts also the THSA PN 47147-700 as the introduction of the CSP does not change

the material of the ballscrew.

This Service Bulletin is published to advise operators of A330-300 aircraft of the issuance of Goodrich

Actuation Systems Service Bulletin No. 47147-27-18 which defines the acceptable corrosion on the

lower splines on the THSA screwjack.

Accomplishment of this Service Bulletin permits to detect corrosion and contributes to ensure the

reliable function of the THSA.

SERVICE BULLETIN

C. REASON

(1) History

Some Trimmable Horizontal Stabilizer Actuators (THSA) PN 47147-500 have been found

with corrosion affecting the ballscrew lower splines (between the tie bar and the

screwjack).

Investigations have identified the root cause for the corrosion :

- Contact/friction between the tie bar and the inner surface of the ballscrew leads to

the removal of Molykote (corrosion protection) in front of the tie bar splines,

- Humidity ingress initiates surface oxidation starting from surfaces where Molykote is

removed,

- Water retention in lower part leads to corrosion spread out and apparition of a

brown deposit (iron oxide).

(2) Objective/Action

This Inspection Service Bulletin requires an inspection of ballscrew lower splines on all

THSA PN 47147-500 older than 11 years since retrofit -400 (or -400 new).

This inspection impacts also the THSA PN 47147-700 as the introduction of the CSP

does not change the material of the ballscrew.

This Service Bulletin is published to advise operators of A330-300 aircraft of the

issuance of Goodrich Actuation Systems Service Bulletin No. 47147-27-18 which defines

the acceptable corrosion on the lower splines on the THSA screwjack.

(3) Advantages

Accomplishment of this Service Bulletin permits to detect corrosion and contributes to

ensure the reliable function of the THSA.

(4) Operational/Maintenance Consequences

None

D. DESCRIPTION

To accomplish this Service Bulletin it is necessary to :

WARNING: MAKE SURE THAT YOU OBEY ALL THE WARNINGS AND ALL THE CAUTIONS

INCLUDED IN THE REFERENCED PROCEDURES.

CAUTION: ALWAYS OBEY THE PRECAUTIONS THAT FOLLOW TO KEEP

ELECTRICAL WIRING IN A SATISFACTORY CONDITION (ELECTRICALLY

AND MECHANICALLY SERVICEABLE). WHEN YOU DO MAINTENANCE

WORK, REPAIRS OR MODIFICATIONS, ALWAYS KEEP ELECTRICAL WIRING,

COMPONENTS AND THE WORK AREA AS CLEAN AS POSSIBLE. TO DO

THIS :

- PUT PROTECTION, SUCH AS PLASTIC SHEETING, CLOTHS, ETC; AS

NECESSARY ON WIRING AND COMPONENTS.

- REGULARLY REMOVE ALL SHAVINGS, UNWANTED MATERIAL AND

OTHER CONTAMINATION.

THESE PRECAUTIONS WILL DECREASE THE RISK OF CONTAMINATION
