Subject: Main Rotor Attach Screws
Date: December 17, 2015
When attaching the starflex to the rotor mast, two different part numbers of screws are used.
It is important that the screws with provisions to attach the droop stop retainers are positioned between the arms of the starflex (not in line with the sleeves).
Failure to follow this proceure will result in the droop stop ring not being able to transfer blade flapping forces to the other two blades. This can result in significant damage to the droop stop retainers and also the rotor mast.
