A BD-5J Acrojet Static Display
Motivating kids toward careers in aviation

Author's note: As a kid, I had a chance to get "up close and personal" with the then-new BD-5. In 1974, Bede Aircraft's first prototype of the airplane, N500BD, was on display at the EAA Museum on Hales Corners, WI, and my cousin Bob was one of the museum's maintenance technicians. My parents took my sister and me to visit both the Oshkosh convention and the museum. I remember standing utterly rapt as Jim Bede wowed the crowds at Oshkosh with his plane-side presentation on the new jet version of the airplane called the BD-5J.
 
Back at the museum, cousin Bob invited me to sit in the cockpit of the prototype BD-5, and he closed the canopy. What you cannot see in the photo below is the aviation passion that was rapidly forming in my brain -- a passion that would last a lifetime.
 
This is the story of my efforts to create a BD-5 static display that might somehow, someday light an aviation fire in some child's mind -- just like it did for me.


July 1974: The EAA was lucky they didn't leave the keys in it,
or I would have flown it right out of there.
 


With my own childhood experience as my inspiration, I set about to create something that might motivate the next "aviation generation." I wanted to keep it relatively simple and inexpensive. What better than a real BD-5 (albeit a non-flying one)?
 
In the summer of 2013, I began looking for a suitable airframe.
 
My first thought was to find the same Honda-powered BD-5 that I'd been fortunate enough to fly in college. It had been built and flown by a local flying group, and although various members of the group flew it for almost a year, it was unfortunately a victim of persistent carburetion and fuel flow issues, a limited budget, group politics, insurance regulations, and various other factors. Due to liability fears, the group grounded the airplane permanently, and in the late 1990s I'd heard that it ended up in the back of a dusty hangar in Florida. Alas, I was never able to track it down.
 
In the fall of 2013. I was surfing around eBay and saw a BD-5 display airframe up for auction in Kansas. The airplane had no powerplant, prop, or drive system, and it was in somewhat rough shape, but in the photos it looked like it was good enough for my display purposes. It had landing gear, a cool tinted canopy, and easily-removable wings. The bid was at $800. I put in a maximum bid of about $1000, and watched in fascination as the bidding went up to something well north of $3,000. I chalked up this absurd selling price to some kind of mental disorder by the winning bidder, and I promptly put the airplane out of my mind. I resumed my search. Most of the airframes I found were bare shells that would require way too much work to make display-worthy.
 
Nearly six months later, I received an email from a man in Kansas. He said, "Are you still interested in my BD-5? My buyer backed out of the sale and refused to pay me. So you can have it for your highest bid." I felt a wave of excitement come over me. After chatting with him about the airplane and its condition, I agreed to buy it.
 
The following weekend, I rented a box truck and drove 650 miles to Smith Center, Kansas, a small town located very close to the geographic center of the United States. The BD-5 had been on display in the front window of an antique mall in the town -- an antique mall that had closed and was now mostly gutted. The mall owner knew almost nothing about the airplane's history, but said he'd purchased it from a group of aviation guys that, to me, sounded suspiciously like an EAA Chapter.
 
With great anticipation, I walked into the littered remnants of the store to find this:

 
It clearly had some issues, but it certainly was a BD-5, and I saw its potential. Rather than spend a lot of time examining and pondering my purchase, I wanted to get it loaded and be on my way. I had a long drive ahead. Since the airplane's nosewheel axle was missing and one of the main tires was flat, we had to manually lift and shove the airplane up the truck's ramp and tilt it to get it through the door. It was not an easy job for two people, but we got it loaded and tied down within about a half hour. I wrapped the wings in blankets for the long ride home.   

 
As you might be able to discern from looking at those blankets, the airplane had a set of short "A"-wings rather than the longer "B"-wings. This, along with some other issues I'd seen during my brief look at it, suggested to me that this had never been a flyable airplane. Les Berven, Bede Corp's chief test pilot, once said during his evaluation of the early model BD-5s that "no one should fly the A-wings, ever." So I was pretty certain that my new toy had always been a display-only airplane. This was confirmed without a doubt after I got the airplane home and began to go through it in detail.

Some previous owner had made a good-faith effort to make the airplane suitable for a parade float or other public display. They had fabricated a set of fixed, spring-steel landing gear legs that looked decent enough. These were attached to the bottom of the fuselage and tubular wing spars with carriage bolts. There was also a wooden insert in the prop-drive housing that had once supported a dummy propeller attached to an iron pipe. The propeller had been lost long ago:

 
The fuselage sides were fitted with fake exhaust pipes. These pipes were welded to steel plates, which were then pop-riveted to the inside of the skin. It was a pretty good illusion, but very crude:


I made a list of the big issues I would need to address before I even contemplated displaying the BD-5 in public:

1. The engine bay and cockpit contained about 2 inches of dirt, leaves and crud.
2. The canopy support bars were badly twisted, and the canopy did not close all the way. The upper aft part of the canopy was cracked and broken, with several large chunks of it missing. The fuselage skin surrounding the canopy support channel was damaged. The leading edge of the vertical stabilizer and the nearby fairing had also been damaged by the canopy.
3. There were several areas where the monocoque structure of the fuselage was compromised by large strings of missing rivets, or blind rivets that had been pulled without going through the underlying structure, but only the skin.
4. There were long strings of missing rivets on the horizontal stabilizer. I later learned that the outboard 2 feet of the stab spar was missing entirely.
5. There was a copious amount of automotive body filler everywhere, and it had not been applied with much skill.
6. The wing fairings were in very poor condition.
7. The wheels and tires needed repair.
8. The paint was old, faded, and peeling off in many locations.
9. The fuselage skins and wing skins had numerous small dents and ripples.

I would also have to do some cosmetic restoration of the cockpit. It had been fitted with a stock instrument panel, some old instruments, and a set of semi-realistic controls, but everything was grimy and corroded. The flight controls were not hooked up. In fact, someone had fixed the ailerons, rudder and elevator into position with nails and pins. The carpet and homemade uphosltered seat were suffering from dry-rot and mold.

Over the course of two months, I took apart everything that could be taken apart, and began cleaning, repairing, and priming. My goal in most cases was to preserve, rather than doing a total rebuild of the structure.

First, I got the wheels and tires fixed so I could roll the plane around the hangar. (The tires were knobby lawn-tractor deck tires, but I kind of liked them. I thought I might replace them later with more realistic aircraft-type tires, but for now, they work OK.)


Many of my friends heard about the new arrival on the airport, and encouraged me to restore the airplane to airworthy condition, thinking it would be as simple as "putting an engine in it" and launching into the wild blue. Usually, after I finished laughing, I would simply show them a few examples of the horrendously non-airworthy workmanship that had gone into this airframe, and they understood why
this BD-5 was never going to be a candidate for restoration to flight. Here, you can see a line of blind rivets on the left side that was supposed to attach the skin to the bulkhead, but never made it all the way through the bulkhead:

 
There were many, many other examples of the haste with which this poor BD-5 had been slapped together, using non-standard hardware and iffy construction practices.

The first significant repair I had to do was aft of the cockpit, where the canopy and its support rod had repeatedly smacked the vertical stabilizer and the fuselage skin. It had also knocked some holes in the VS-to-fuselage fairing. As I began to remove the paint in this area, I found lots of pre-existing, crudely-sanded body filler:


 

I patched the holes in the fairing with lightweight fiberglass cloth and resin. You can also see that I'd begun to patch some of the dings in the skin with SuperFil filler (the blue stuff in the following photos). I filled and sanded this whole area for several days to get it smoothed out. It was pretty wavy and ugly to start with:

 
Surprise, surprise! Under the paint, I found wood in several places. The wingtips and the tip fairings on the vertical stabilizer, rudder, and stabilator were made of wood that had been carefully sanded to match the airfoils' contours. I was actually pretty impressed with the craftsmanship of these tips, so I left them in place. They just needed some filler to make them perfectly smooth and pinhole-free:


Another structural problem appeared when I got to the all-moving horizontal stabilizer. It was moving all right -- in fact, it was almost floppy. You could grab the end of the stabilator and move it up and down 6 inches. The structure had very little stiffness to it. I began stripping the paint off, and found that there were no rivets in the skin in the outer two "bays" along the spar. I shoved a 3-foot long borescope camera inside the stab, and found there was NO spar in those outer bays! Someone had just filled the empty skin holes with body filler and pressed on with their paint job. The skin certainly provided enough stiffness to look good enough for a parade float, but it made the tail section a bit delicate. How the spar came to be truncated like this will remain a mystery. I thought about disassembling the whole stab and fabricating a new spar, riveting it back in, and re-skinning the whole thing -- but frankly, I wanted to get this entire project done within a month or two and a budget of perhaps $2,000, and I was already past both my time and expense estimates. I decided to leave it alone.


Presto -- a couple of nice little cover plates, and there were no more exhaust pipe holes:


Straightening out and re-bonding the trailing edge of the rudder took every side-grip cleco I had:

 
The wing-root fairings were very crudely-built, and were in poor condition. I spent many hours filling, patching, sanding, and reshaping them to be acceptable for even a static-display airplane. They're still not great, but from a few feet away, you can't really tell. (Shhh...it's our secret.)


During the body-work phase, I'd been contemplating how I wanted to display this airplane. It had super-short "A"-wings, so it wouldn't look quite right as a BD-5B or BD-5D. And what to do about the missing propeller? Hmmm. The gaping hole at the back end of the airplane began to gave me an idea:


"It kind of looks like a jet nozzle... Hey, that's it! Let's make this thing a -J model!"

In a flash, I had the whole thing planned out. I would paint the airplane as a tribute to Corkey Fornof and Bob Bishop, whose "Sonic Acrojets" formation team was one of the formative airshow acts of my teenage years:

I took some measurements and made some sketches, and took the drawings down to a local machining company. Two weeks later, they handed me this:

 

 
The billet aluminum exhaust nozzle looked great! I marked it, drilled it to the fuselage, and put it aside for later assembly after the painting process. So now I had an exhaust -- but I needed intakes. In a real BD-5J, the intakes are located just below the aft edge of the canopy -- pretty far forward along the sides of the fuselage. I realized that installing a pair of NACA intake scoops at that location in this airframe would be a very time-consuming project. So I took the lazy man's way out and decided to install them in the engine access doors, about 14" aft of their proper location. (Hey, the BD-5 is an experimental airplane, right? A builder is allowed to modify things...) I purchased a set of nice carbon fiber NACA scoops from an online automotive supply catalog. These components turned out to be the single most expensive part of this project. You don't want to know how much I paid for those suckers. I cut the inlet holes and flush-riveted the scoops. They looked pretty good, if I do say so myself. Here they are, being prepped for priming:


After monkeying around with the center canopy support arm for a few days, I pronounced it un-repairable. I built my own replacement from scratch, using my original set of BD-5 plans as a reference. Who knew I'd ever have a chance to use them for something like this? It was a very fun and nostalgic experience.

After removing the instrument panel and seats, I gave the fuselage and wings a final sanding and cleanup, then primed the exterior with white rattle-can primer. I also painted the cockpit and detailed the side control quadrants.


Just for fun, I test-fit the jet nozzle. (Yeah, it doesn't have the proper BD-5J reverser buckets on it, but I think it looks pretty good anyway. It will do nicely for its purpose...)


Next, we towed the plane down to my friend Bill's hangar, where the painting would be done:

 
Over the next week, my good buddy Bill spent his afternoons spraying the paint. His help and expertise were absolutely critical, since it's well known that I absolutely HATE painting airplanes. Here, the white base coat has been applied:


One part of the painting process I actually enjoy is tape masking, so I took care of that myself:


 

 

 
While Bill painted, I worked on the instrument panel, seat, and canopy. On the panel, I cleaned up everything, painted the glareshield and installed a new edging strip, and labeled some of the controls and switches.

The seat, which consisted of two pieces of fabric-and-foam covered plywood, was a rotting, mildew-ridden mess. The existing seat-back was also, inexplicably, too tall -- and when it was in place, the aft canopy attach point actually rested firmly on it (which might have caused the canopy to break in the first place). So I made new plywood seat parts and re-upholstered both of them with new foam and new fabric. I also bought a scrap piece of new carpet and trimmed it to fit, using the nasty old carpet as a template.

I also spent quite a bit of time repairing the cracked and broken canopy. Basically, I made a curved, 4"x6" plate out of 0.032" aluminum, painted it flat-black, and then bonded it onto the outside of the canopy, at the aft edge. Then I drilled the canopy rod attach point to this plate, and used new hardware to attach it. So the plate not only serves as the attachment point for the aft canopy support rod, but it hides the cracks and small holes in the canopy. Because the canopy is darkly tinted, you can hardly see the plate. And if you do see it, it looks like it's supposed to be there.

A few days later, Bill said the paint job was finished! I headed over to his hangar and marveled at the awesome job he did. I towed the plane home and installed the engine access doors (using new stainless screws and finish washers), attached the exhaust nozzle, and installed the instrument panel and seat. I also painted the landing gear and wheels, and added a few details such as an "Experimental" decal inside the cockpit.

So, without further ado, let's here's my new "faux BD-5J" display plane:


 

 

We towed her over to the local EAA hangar, and she made her public debut in August 2014 at one of the Chapter's pancake breakfasts. I was happy to see the overwhelmingly positive reaction from local residents and airport bums alike. (Note the nearby signs that explain the history of the BD-5, and how this particular one was restored for display. I think it's important to have good, informative signage next to airplanes that are displayed to the non-flying public.)


 


The "BD-5J" has now been on display at many of our EAA Chapter's monthly pancake breakfasts since August 2014, as well as the chapter's membership meetings. I always encourage kids to have their photo taken with it and, if the child is small, I will lift them inside for a cockpit photo, too! The kids really love the BD-5, because it's just their size.

No, mine is not a perfect BD-5J display. It's more of an artistic interpretation of a BD-5J. But I hope I've given you some ideas for a simple static-display airplane that you could create on a limited budget, in order to motivate kids toward aviation. There are quite a few derelict and forgotten old homebuilt airplanes out there. Frankly, if a homebuilt was built in the 1960s or early 1970s, its useful life might very well be coming to an end, and its original owner/builder is probably nearing the end of their flying career. So keep your eyes and ears open for opportunities like this. And it certainly doesn't have to be a BD-5.

You never know what seeds you are planting in a kid's mind. Someday, that kid might grow up to be a pilot, mechanic, aircraft builder, ATC controller, flight school owner, instructor, aerobatic competitor, airshow enthusiast, photographer, artist, writer, astronaut.... You just never know. I had no idea when I sat in that airplane in the museum many years ago where that road would take me. Pay it forward!

Postscript: I have made a few additions to the airplane since I finished it.
1. Applied arrow decals saying "Danger -- Jet Blast" just in front of the exhaust nozzle.
2. Painted simulated fuel caps on the tops of the wings and applied "Jet Fuel Only" decal rings around them. You can just barely see them in the photo above.
3. Installed aluminum ducts inside the inlets and exhaust that give the illusion that you are looking into an intake plenum or into the jet engine.
