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 A340-200/300 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.

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
