Flight controls - Rudder servo control spring rods (ATA 27)
APPLICABILITY :
AIRBUS INDUSTRIE A300, A310 and A300-600, all certified models, all serial numbers except for :

REASONS:
Cases of jammed rudder servo control spring rodscaused by heavily corroded internal mechanism parts and clogged drain holes have been reported on in-service aircraft.
Simultaneous jamming of 2 servo-controls (out of the 3 which the rudder includes) would make it necessary for the crew to take a corrective action.
ACTIONS :
Before June 30, 2000:
Replace the spring rods in accordance with the instructions of AIRBUS INDUSTRIE Service Bulletin A300-27-0182 revision 2, A310-27-2065 revision 2 or A300-27-6023 revision 2.
