1.A.2.b SA330 helicopters 

Main servo-controls which have been overhauled or repaired at UTC Actuation Systems / Goodrich 

Actuation Systems at Vernon (France) between June 01, 2008 and September 15, 2012, and which bear 

the following part numbers: 

- SC7111, SC7111-X (X for all part numbers)

OR 

Helicopters equipped with servo-controls whose part numbers and serial numbers are specified in 

Appendix 1. 

1.B. ASSOCIATED REQUIREMENTS 

Not applicable. 

1.C. REASON 

Revision 0: 

EUROCOPTER has been informed of missing crimping on ball joints of servo-control end-fittings. 

The slipping of the ball joint of the upper end-fitting of the PUMA and SUPER PUMA main servo-control can 

lead to a significant reduction in the service life of this end-fitting. 

The slipping of the ball joint of the lower end-fitting of the PUMA and SUPER PUMA main servo-control does 

not significantly affect the service life of this end-fitting. 

Consequently: 

EUROCOPTER has made the check for crimping of the ball joint of the upper end-fitting and then, if 

necessary, the return to conformity of the crimping of the ball joints of both the upper and lower end-fittings 

of the servo-controls concerned, mandatory. 

Revision 1: 

The purpose of Revision 1 is to specify that the additional list of main servo-control serial numbers given in 

the Appendix is an additional effectivity condition which is independent from the affected servo-controls listed 

in paragraph 1.A. 

Consequently, the “AND” condition of paragraph 1.A. has been replaced with the “OR” condition. 

Furthermore, Revision 1 specifies in the effectivity paragraph that only the main servo-controls which have 

been overhauled or repaired at Vernon (France) are concerned by this ALERT SERVICE BULLETIN. 

Revision 1 of this ALERT SERVICE BULLETIN affects compliance with Revision 0. 

1.D. DESCRIPTION 

- Visual check of the ball joint of the main servo-control upper end-fitting.
