1.
UPPER
LATCH There
are
three
points
that
should
be
inspected
and/or
adjusted
on
the
upper
latch.
a)
Check
to
ensure
that
the
upper
latch
mechanism
is
over
center
when the
door
is
latched
rRef.
Figure
21,
Sheet
1
of
4).
This
can
be
accomplished
by
using
a
small
inspection
mirror
to
see
that
the
upper
operating
link
is
against
the
adjustment
screw
and the
forward
edge
of the
upper
operating
link
Is
forward of
the forward
edge
of
the lower
operating
link.
If
the latch
mechanism is
not
over
center
when
the
door
is
latched,
adjust
the
over
center
stop
screw.
b)
Check
to
ensure
that the
upper
latch
hook
pin
is
positioned
so
that
it is
almost
touching
the
aft
portion
of
the hook without
riding
on
the
hook.
If
the
upper
hook
does
not
properly
engage
the
pin,
move
the

latched,
leaving
a
noticeable
gap
between
the door and
the
