## The airworthiness directive

59-05-06 SUD AVIATION: Applies to All Alouette II SE 3130 Helicopters Prior To Serial Number 1160 Except Serial Number 1085.

Compliance required as soon as possible but not later than May 1, 1959.

In order to preclude binding between the uniball bearing and oilite bearings at the main rotor swash plate, replace oilite bearings Sud Aviation P/N 68.10.009 and spacer P/N 68.10.010 with new oilite bearings P/N 68.10.014, spacer P/N 68.10.012, shim P/N 68.10.013, spacer P/N 68.10.012, shim P/N 68.10.013, spacer P/N 68.10.011. (Note: This assembly must also be lubricated every five hours with Mil. L.644A oil in accordance with Sud Aviation Maintenance Manual.) The French SGACC considers this mandatory. The FAA concurs with this action and considers compliance therewith mandatory.

(Sud Aviation Service Bulletin AL.68.11.159 and modification proposal V-49 cover this same subject.)

In addition, modifications stated in Republic Aviation Service Bulletins 3.45-1, safetying lateral trim cylinder cap nut and 8.10-3 on rework of emergency fuel shutoff lever must be accomplished immediately unless already completed.

This supersedes AD 59-02-03.
