Installed the main rotor thrust bearing and bearing flanges in the hood bracket of the airframe. It was necessary to trim the back edge of the flange a smalll amount to allow adjustment of the fore/aft position of the main rotor mast. I aso had to elongate the bolt holes fore/aft in the hood bracket to allow movement of the bearing flange. 3.0 of the above hours performed on 3/5/04.
