____________________________________________________
1. General_______
A. This procedure provides instructions for removal/installation of all strut attach pin/bolts with the engine removed or installed. If a midspar pin is to be removed, both upper link pins/bolts and both diagonal brace pins/bolts must be installed. Only one midspar/spring beam pin is to be removed at a time. Both upper link pins/bolts or both diagonal brace pins/bolts may be removed simultaneously but only one link should be free at any one time, unless nacelle strut is to be removed.
