FLIGHT CONTROLS - ELEVATOR SERVOCONTROL

NEW EYE-END WITH INTEGRATED ROLLER BEARING

1. Planning information.

A. Effectivity.

(1) This Service Bulletin concerns Elevator Servocontrol

PNR 31075-SERIES.

B. Concurrent requirements.

To further increase the robustness of the servocontrol bearing,

it is also advisable to embody Service Bulletin 31075-27-17 (on

body side only) at the same time as the present one.

C. Reason.

The roller bearing (greased) technology is in use on other UTAS

flight control units fitted on various A/C programs and has proven

to exhibit a better behavior compared to Teflon coated bearings

technology (less play, lower friction over the service life

etc...)

Roller bearing positive feature helps at improving the airframe

vibrations situation.

Additionally the repetitive inspection as per Aircraft SB

A320-27A1186 and VSB 31075-27-21 will not apply to servo control

fitted with post SB 31075-27-22 roller bearing eye-end.

D. Description.

This Service Bulletin introduces a new Eye-End with an integrated

roller bearing replacing the Eye-End with integrated self

lubricating spherical bearing (Teflon coated bearing).

The new Eye-End with an integrated roller bearing is fully

interchangeable with the Eye-End with integrated self lubricating

spherical bearing.

E. Compliance.

This Service Bulletin introduces a product improvement

modification.

Embodiment is recommended on an opportunity basis at the option

of the operator.

A fleetwide retrofit campaign will be launched for a four years

duration from Airbus SB issuance. Refer to Para 2. ”Material

information” for further details.

F. Approval.

The technical content of this document is approved under the

authority of DOA N EASA.21J.031

Service Bulletin N A320-27-1223.

Under no circumstances shall the modified equipment, resulting

from the application of this SB, be installed on the aircraft

type unless the corresponding modification, and if applicable,

its aircraft SB are approved.

L. Publications affected.

The Component Maintenance Manual (CMM) 27-34-52 will be updated

in accordance with this service bulletin.

Technical information here-below are given prior to the next
