Bo 105 CBS
Screw the rear mechanics support to the inserts mounted on bulkhead 4 using M3 x 16 socket-
head cap screws. Adjust the position of the mechanics and bulkheads so that the main rotor
shaft exits the top of the fuselage exactly on the centreline. Check this by placing the upper
fairing on the fuselage and viewing from the front.
Mark the position of the bulkheads in the fuselage, then roughen up the joint areas - after
removing the mechanics again temporarily - and finally glue the bulkheads 2, 3 and 4 to the
fuselage shell, with the mechanics installed. Check that alignment is correct before leaving the
resin to harden.
Allow the epoxy to cure fully, then undo the four mounting screws and lift out the mechanics.
Check once more that the skid bars are central in the fuselage, then fix them in the brackets by
fitting a 2.2 x 9.5 mm self-tapping screw through each of the holes.
