GEAR
There
are
4
ways to
lower
the gear
on
a
B-24.
It
is
seldom
that
all
4
fail.
Recently a
pilot
flew
around
for
2
hours
trying
to figure out
with
an
ignorant
engineer
how
to
get
the
gear
down.
Then,
with
5
minutes
of
gas
left,
he executed
a
belly landing which
did
$75,000
damage.
Inves-
tigation
showed
that
60
seconds
of
know-how
would
have
put
the
gear down.
Know
all
emergency procedures.
Rehearse
them
with
your
engineer
and copilot. Take
an
afternoon and
crawl
around
the
airplane
with
them.
Read each
procedure and
dry-run
it
on
the
spot.
That's the way to
get acquainted
with
your
airplane. Then,
if
an
emergency
arises,
you'll
be ready.
1.
Place
the landing
gear
control lever
on
the
pilot's
control
pedestal
in
the "DOWN"
posi-
tion.
METHODS
OF
LOWERING
THE
LANDING
GEAR
1.
Normal hydraulic
operation.
2. By
use
of the
auxiliary
hydraulic
pump.
3. By
use
of
the

2. Turn
the
emergency
hand
crank
clockwise
until
the main
gear
is
down
and
locked.
(This
requires approximately
30
turns.)
The crank
is
on the
forward
side
of
the
front
spar and may
be
reached
from the
extreme
forward
end
of
the bomb

catwalk.
