at the blade cutouts, and remove the spinner dome from the propeller. Do not remove
the screws attaching the stiffeners at the blade cutouts to the rear bulkhead.
NOTE: Do not remove the screws attaching the front bulkhead inside the spinner dome
(the screws approx. at half the height of the spinner dome). Remove the spinner
dome and front bulkhead as assemly.
If the screws attaching the spinner dome to the front bulkhead were removed by mistake,
remove the spinner dome and the front bulkhead from the propeller. See marking 1 to 5
inside the spinner dome (near the blade cutouts) and on the front bulkhead (near the rim)
and reinstall the front bulkhead into the spinner dome. Be sure that all screws are properly
tightened.
NOTE: Information on the screws attaching the spinner dome to the front bulkhead is not
applicable to models, where the front bulkhead is riveted to the spinner dome (no
screws in the area of the front bulkhead).

Remove all existing screws attaching the spinner dome to the rear and front bulkheads and
to the stiffeners in the blade cutouts, and remove the spinner dome from the propeller. Do
