the
cockpit,
check
that
the
landing

switch
ON. Check the

be
free
and
move
properly.

lines through
the
drains located
on
the

to
check
during the
walk-around
is
to
ensure
that the
crossfeed
drains
are
closed.
Check
the
right wing,
aileron
and
flap
hinges
and

ice. Make
a

properly
inflated
and
not
excessively
worn.
The

tip
and
leading
edge
should
be
free
from ice
and
