Fit the striker plate
Place the striker plate onto
the latch pin on the door
with the rounded corners
facing into the cabin as
shown at right, then close the
door until the rear of the
door is flush with the
fuselage and carefully mark
the location of the striker
plate on the door jamb.
Mount the striker plate to the
door jamb in the marked
position using countersunk self-tapping screws and drill the centre hole through the fibreglass.
Fit the door jamb
Now you will need to mark a line around the opening to locate the jamb: there needs to be an
allowance made for the thickness of the door skin plus 2 compressed layers of door seal: one
seal (white) is glued to the door and one (black) is glued to the jamb. Note that the seals are
glued in place
after
painting is complete – do not mount them at this time.
Make up a gauge to mark the position of the door jamb: in the factory
we use a simple plastic block that is 28mm from front to back (which
is the width of the jamb plus the compressed door seals) with a screw
as a handle as shown in the photo at right.
With the door taped or held flush at the top and bottom (the front is
now held by the hinges and the back is now held by the latch) hold
the gauge against the inside of the door and mark a line around the
opening with a pencil held against the back of the gauge.
The resulting mark around the opening will allow for the varying
thickness of the door skin, which is thicker
around the hinges.
There are pre-formed top and bottom jamb
sections for each door: mount the inside of
each jamb on the line that you have just
marked using countersunk self-tapping screws
at 100mm centres.
Start from the striker plate and work your way
around the opening drilling, countersinking
and fitting one screw at a time until you arrive
at the front of the opening at the top hinge. The
gap between the top and bottom jamb should
be enough to clear the top hinge arm.
Each screw hole should be countersunk just
enough to place the head of each screw
slightly below the surface of the jamb.
