Fit the key lock
Remove the bottom section of the door jamb and set aside for the moment.
Mark a position 30mm out from the rear of the opening and 130mm up from the bottom of the
opening and drill a pilot hole, then drill out to 18mm and elongate the hole with a round file
until the door lock barrel can be mounted snugly into the hole.
Now mark and cut a slot 60mm long and 6mm wide 20mm in from the fuselage skin in the
door opening, with the bottom of the slot square with the bottom of the lock hole. This is the
slot that the lock arm will operate through. Close and latch the door and mark the slot onto the
back of the door – use a builder‟s pencil or any similar thin marker and mark through the slot.
Mark and cut the slot into the door jamb and then refit the door jamb.
Cut the slot in the back of the door and check that it matches the slot in the door opening.
Fit the lock barrel into the elongated 18mm hole and secure with the large retaining nut then
fit the lock arm, which may need to be bent slightly in order to swing freely into the slot.
Turn the key so that the top of the key moves forward and fit the arm in the locked position.
Test that the door can be locked and unlocked with no binding of the lock arm.
Leave the doors fitted for now, they will be removed later in
