Rev. 17 Apr/20
Shortly after engine start-up, with the propeller RPM above
800, the latch pins in the start lock units will still retain the
blade angle. To release the latch pins, it is necessary to
manually actuate the propeller slightly toward reverse. This
will move the clamp-mounted plate, allowing the latch pins to
slide freely. Centrifugal force will compress the springs and
disengage the pins from the plate.
