SBD
Checkout
Very few of these Douglas SBD-5 Dauntless dive-bombers
are left, and even fewer are flying. The Dixie Wing of the
Commemorative Air Force has one, and it provides a very
memorable checkout at Falcon Field in Georgia.
There are no more than a handful left.
You can count the ones that are currently airworthy on one
hand, and the ones that are flying regularly can be counted on
the fingers needed to hold a good cigar. Of the more than 5900
built between 1940 and 1944, that's all there are in the
world. I am privileged to be one of the latest airman to
discover the fine flying qualities of the Douglas SBD-5
Dauntless dive-bomber.

Dauntless dive-bombers achieved fame and notoriety
(depending on which side of the Pacific you were standing on)
during the Battle of Midway. Lt. Cdr. Wade McClusky, leading
33 SBD-3's of VB-6 and VS-6, by a stroke of luck in sighting
the Japanese destroyer Arashi and following it, located
the main Japanese Carrier Strike Force and sunk three Japanese
carriers with help from SBD's from VB-3. In only three
minutes, these three squadrons, VB-6, VS-6 and VS-3, sealed
the fates of three Japanese fleet carriers, the Akagi,
Kaga and Soryu, and turned the tide of the whole
Pacific war. Not too shabby a performance for an airplane that
was considered too slow, under-armed and pretty much already
obsolete by the time of the Japanese attack on Pearl Harbor.
Design and Construction
The Dauntless design was conceived by Ed Heinemann of
Northrop Corporation, first as the XBT-1, then the
much-improved XBT-2, first tested in 1938. The XBT-2 was
significantly damaged in a landing accident, and returned to
the factory for repairs. By that time Heinemann had gotten
permission to replace the original Pratt & Whitney and
two-blade propeller with a Wright Cyclone R-1820 and a
three-blade prop. In addition, he added the leading edge slots
and different ailerons and elevators. The result was a vastly
improved airplane that became the prototype Dauntless. While
all that was being done, the Northrop Corporation was
dissolved and became the El Segundo Division of Douglas, which
had owned 51 per cent of the Northrop stock. The contract for
the reworked dive bomber was placed with Douglas in April of
1939, and the first production Douglas SBD-1 Dauntless was
delivered to the Navy in September, 1939.
Dauntless aircraft were produced from 1939 until July of
1944. The variants were numbered SBD-1 through SBD-6, and the
Army flew them as A-24's through A-24B. The version that sunk
the Japanese aircraft carriers during the battle of Midway was
the SBD-3. The version that I get to fly has been restored to
being an SBD-5.

"My" airplane was built in El Segundo as an Army A-24B. As
far as we know, it never saw combat, and after the war it was
sold to a party in Mexico (along with several others) who
converted them into photo ships by removing most of the
workings in the rear cockpit, cutting out some structure in
the belly just behind the cockpit and installing a big camera
window. That also required the re-routing of the rudder
control cables, as they are supposed to go down the center of
the empennage. The airplane returned to the U.S. sometime in
the early 1960's, and was eventually acquired by the
Confederate Air Force in Harlingen, Texas, now known as the Commemorative Air Force, headquartered in
Midland, Texas. Members of the CAF flew the airplane for a
number of years without much changing it from its Mexican
configuration, until it was determined to be unsafe and
retired. The CAF put the airplane up for adoption, and it
eventually came to the Dixie Wing of the CAF currently located at
Falcon Field
in Peachtree City, Ga. After an extensive eight-year
restoration, with many parts being built from scratch, the
airplane was transformed into a very authentic SBD-5.
Refurbished and Updated, Slightly
The aircraft is currently painted and armed (just dummies,
of course) as it would have appeared during the Battle of the
Marianas in June, 1944, also known as the "Marianas Turkey
Shoot." About the only nod to modern airspace requirements is
the single VHF com, transponder with Mode C, a VFR
panel-mounted GPS, and two modern-style gyros. Everything else
in the cockpit would have been found there in 1944. The rear
cockpit is even more original, with only a vertical card
compass and headset jacks to give away what year it is. The
twin 30 caliber swivel mount machine guns are in place with
ammunition belts feeding to both, and they are fully stowable
and operational except for the little detail of not being able
to fire. The twin 50's sticking out the front cockpit have the
same drawback. Under the wings there resides a 1000 lb. bomb
in the center shackle, and two 100 lb bombs on the wing racks.

show.
This airplane is what brought me
back to the CAF after an absence of many years. During the
intervening years, I've owned my own T-6 and for a while a
C-45, and built up about 900 hours of T-6 time and 120 hours
in the C-45. I got introduced to the SBD and the Dixie Wing at
an air show at Maxwell AFB in Montgomery, Alabama about 3
years ago, and had a very pleasant experience visiting with
the Dixie Wing members present. I was cordially invited to the
hangar at Falcon Field (KFFC) to have a look around and meet
some more members. Eventually I did get around to it, and was
very impressed by the level of commitment the members had
toward their airplanes, and the graciousness with which I was
treated. My experience with CAF many years ago was nowhere
near as pleasant. It is a changed organization in more than
name. I decided to join up. Having recently sold my businesses
and acquired that rarest of all commodities, time, I began to
go to the hangar on a fairly regular basis. I really had no
intention of trying to fly the Dauntless in the beginning, as
there were three very competent pilots already on the
airplane, and I did have two of my own to fly (the T-6 and the
Twin Comanche). As time passed, however, one of the pilots
suffered a stroke, and another a heart attack. This left one
poor guy to do over a dozen air shows all by himself, and he
still has one of those pesky jobs that require him to show up
to work from time to time as well. I know, I know, you're
thinking that ain't sounding so bad, but trust me, taking an
airplane like this to an air show, while fun, is still a lot
of work and represents a lot of time away from home. My very
understanding wife gave her blessing to me sponsoring the SBD
and getting checked out in it, and the Wing leadership seemed
to think it was a good idea, so I sent off my sponsorship
check and began the process.
Time for a Checkout
No one in their right mind is going to let a pilot of
unproven skills get in what is almost a one of a kind airplane
without some sort of evaluation process. CAF is no different.
Hard and expensive lessons have been learned over the years
about just letting anyone with a pilot's license who can write
a check get into an airplane and fly. There is a set of basic
experience requirements, a series of checkrides that must be
passed and a personal interview with members of the CAF
General Staff that must be done before one gets the
opportunity to crank the engine. The requirements for
different types of airplanes vary, but for the rare and
expensive single engine fighter types they include 200 hours
of T-6 experience and two checkrides taken in the back seat of
a T-6 with two different check pilots specified by the CAF
Operations Officer and the Standards & Evaluations
committee. It took me about 5 months to get all that done,
including a trip to Midland for the interview and one to
Arkansas for the first checkride with Dr. Stan Musick, a CAF
fighter check pilot. It could have been done faster, but when
that many people are trying to mesh calendars, sometimes it
takes more than one try. My second checkride was done with
local CAF check pilot John (Skipper) Hyle, and I was signed
off and ready to start getting seriously acquainted with the
SBD.
On the ramp at Falcon Field.
The weather in Georgia and Alabama this winter has been
what you might call wet. Real wet. Trying to schedule the SBD
checkout was a bit of a challenge, but one rainy day was spent
doing a ground school. I had already become very familiar with
the aircraft manual, but I picked up some operational tips and
reviewed both CAF and FAA regs. pertinent to flying this
airplane, as well as taking a written test. I was also
instructed in how to start the airplane, which I soon found
was one of the more complicated (for me, anyway) things you
can do. We went out and did a thorough pre-flight to
familiarize me with the airplane and I picked up more good
operational tips.
Cockpit Layout

The airplane has some quirks that you have to be familiar
with before you can be comfortable going out to fly it. The
cockpit layout is a bit unconventional. For example, the
throttle quadrant is on the port side where it belongs, but
the gear, flap, dive brake, hydraulic pump control power push
lever and manual hydraulic pump handle are on the starboard
side (hey, this is a Navy airplane, so left is port, and right
is starboard). This means that during takeoff, once you're in
your initial climb, you must take your left hand off the
throttle, grab the stick with it, then with your right hand
select gear up and press the hydraulic power push lever. This
layout is different from the T-6 I'm used to, where everything
you need to move is on the left side. Even though the dive
brake controls are disabled as a requirement of the Limited
type certificate, you still want to be sure you don't grab it
by mistake, as it is right next to the gear lever. Another
little oddity is that the airplane has a sliding desktop
installed under the upper instrument panel. This was so that
Navy pilots could do their navigation plotting in flight and
has a big whiz wheel installed on it. The problem with this
today is that it even with it stowed, it sticks out enough
that you sort of have to duck your head to see the gauges on
the lower instrument panel.
A suitable day finally arrived, and I flew my T-6 from my
home in Alabama up to FFC, helped pull the SBD out of the
brand new Dixie Wing hangar, did a pre-flight and climbed into
the front seat. Pilot Jim Buckley took me out for some taxi
practice first, and the biggest issue there is that the
tailwheel is free castering or locked straight, just like the
Twin Beech. No real surprises, you just have to be careful of
the brakes. They fade fast. It's best to punch the brakes
briefly to turn rather than ride them and make it smoother.
Rougher ride, but the brakes last a lot longer. Visibility
over the nose is comparable to the T-6. After doing that for a
while, we returned to the hangar and shut down. I then
attempted a hot start after only a few minutes of shutdown
time, and botched it twice. The first time I didn't get the
mags on before the inertial starter wound down too far, and
the second time I didn't come off of the primer quickly enough
and she quit after a very brief attempt to start. Part of the
learning experience. After we got her going, I got in the back
seat and Jim took me out for a little air work. As far as
helping me get a feel for the airplane, it was not terribly
helpful. The stick position in the back seat is awkward at
best, and the throttle is very difficult to keep a hand on due
to the location of the gun ring. There's no tach back there
anyway, so I left most of the throttle moving to Jim in the
front seat. I did a few steep turns, keeping the altitude
within a couple hundred feet which is about as good as one
could expect given the lack of vis (there is a piece of armor
plate between the front and rear cockpits, completely
eliminating any forward visibility) and having nothing but an
airspeed and altimeter for instruments in the back. Then I did
a little slow flight with about the same results, and some 60
degree to 60 degree (or at least in that vicinity) banks and
turns. Again, with no gyros and no vis, it was pretty much
seat of the pants stuff. I also flew it a little with the gear
out and flaps up and down and did one simulated go around,
just to get a feel for the pitch changes and torque involved.
Jim took us back to the airport and we swapped seats again.

This time I managed to get it started on the first try, and
am slowly beginning to understand what she wants when hot.
Cold starts are not a problem. The 1820 fires right up when
you get the combination of starter and primer down (and
remember to turn on the mags). It will run quite nicely on the
primer alone, so there's no need to get in a big rush to bring
the mixture up. We taxied out again, and I did indeed remember
to lock the tailwheel before beginning the takeoff roll. The
only thing I forgot was the N number of the airplane. I had
enough new numbers running around in my head that that one
didn't seem real important, and there is no memory jogging
decal in the cockpit. Takeoff was straightforward and without
surprises. I kept the tailwheel down until she told me she was
ready to fly, and it accelerates quite nicely compared to a
T-6. 1200 horsepower will do that. Getting the gear up is no
big deal, except that my T-6 is in "G" configuration, with
hydraulics on demand, so I had to remember the power push to
charge the hydraulics. A little something different, but no
big deal. The first power reduction from the 46.5" x 2500 rpm
takeoff power comes pretty quick. Basically as soon as the
gear is up. Back to 39" and 2300 RPM at 130 mph indicated for
the climb..
She climbs pretty good, despite a ground density altitude
of nearly 2000' that day. Clouds kept us down below 2500', so
I didn't do anything too radical. After powering back to 28" x
2000 RPM for cruise, (that yields about 180 MPH indicated,
with close to a 60 gph fuel burn) I did some more banks, steep
turns, slow flight (with some more power reduction), and a
slow steep turn to the first nibble of a stall. I experimented
with lowering the gear and flaps, did some slow flight dirty,
and just generally got to know the airplane a little bit. I
opened and closed the cowl flaps and oil cooler door, played
with the trim a bit, changed fuel tanks a couple of times and
just generally got more familiar with the locations of the
various levers, knobs and switches. Then it was time to go
back for the first landing.
I got set up on downwind at 22" x 2300 RPM, slowed to gear
speed (145 MPH), lowered the gear (it falls out without
hydraulic pressure required, the tailwheel doesn't retract)
then pumped down about half flaps with the hand pump. Turning
base I slowed to about 110 MPH, and hit the power push to get
the rest of the flaps out and put some hydraulic pressure on
the gear to ensure a lock. I was a tad low, so added a smidge
of power and she touched down about 3 seconds before I was
ready. No too bad for a first landing. It was a wheel landing,
but she tracked straight and the tail came on down pretty
easily as we slowed. Jim wanted me to use the whole runway to
save the brakes, so we rolled to the end, where I remembered
to unlock the tailwheel and got off the runway to do the
post-landing checklist. After cleaning it up we taxied back
for another go. The second takeoff went much like the first,
with smooth and fast acceleration and I flew it off from a
three-point attitude. It sits a little more level than a T-6,
so that doesn't feel awkward at all. I stayed in the pattern
this time but didn't have any trouble keeping up with the
airplane, though I probably flew a little farther out than I
might have if I was real familiar with the airplane before I
turned crosswind. The second landing was better than the
first, as I had a better idea of what the sight picture should
be. It was still a tail low wheelie, but was smoother, and
only happened a couple of seconds before I thought it would.
She is a bit taller than my T-6. I didn't have to add any
power this time either. One more time around with a good
result, and we called it a day. We taxied back and went
through a 2 minute oil scavenge run at 1200 RPM, then shut her
down.
There was a concrete truck waiting for us at the hangar, so
we climbed out, got out of the flightsuits and into the
concrete clothes, and spent the rest of the day pouring and
finishing a concrete sidewalk beside the hangar. Not the usual
way to celebrate a checkride, but it was certainly memorable.
On to Air Shows
My next flight took place about a week later (again, due to
lousy weather), and was my first solo flight. As expected, it
went well and the airplane and I didn't scare each other. I
pretty much repeated my checkout flight, as well as diving a
bit to build up some speed so I could see what the control
pressures are at higher speeds (up to about 235 mph indicated,
on that flight). Since then I've flown her several more times,
including a trip to Columbia, MO for an air show. On that trip
I found she was a dream to fly in formation with the C-45.
I've never flown an airplane before that had enough power that
I didn't have to worry about being sucked (falling behind) and
not being able to catch up. She's light and pretty well
balanced on the stick, but is a bit heavy on the rudder. I
think she'd do real good warbird-type aerobatics, but with the
bombs hung under the belly and wings, I won't do that. Being a
T-6 guy, my basic impression of the airplane is that it's a
T-6 on steroids, but easier to land due to the wide gear track
and longer fuselage. A lot of extra power, a little more
weight, more available speed, but at the cost of twice the
fuel burn of a T-6. In short, she's a pussycat to fly. I'm
honored and grateful to have the opportunity to fly this
airplane.

If you're in the vicinity, stop by the Dixie Wing hangar at
Falcon Field and say hello. We're always glad to show off the
new hangar and brag about our airplanes. In addition to the
SBD, you'll find a C-45 in RAF colors, a PT-26 in AAF colors,
plus a couple of member's airplanes are usually in residence.
Right now there's a beautiful Stearman and an SNJ in the
hangar. In the shop you'll find a T-6D and a P-63 King Cobra
undergoing a ground-up restoration. By July of this year, you
should find a P-51 Mustang in the hangar as well. Yeah, I'm
gonna fly that one, too. Life is
good.
