Bernard Pietenpol was born Febuary 17th 1901 in Jamestown, North Dakota, passed January 11th 1984 in Spring Valley, MN.

From the day he was born  Bernard was a gentleman and a genius and always intrigued with flying machines and mechanical genius. Bernard's personnality was to always help people!  Bernard helped thousands of people. Bernard worked from the early hours of the morning to late at night, often overnight if required.

 

In the early 1920's Bernard designed a  Ford Model T biplane.  Bernard laughed at himself and said; "It would have flown if I'd had known how to fly it. Luckily I didn't."

​

Bernard did learn to fly!  Bernard designed a prototype of the Pietenpol Air Camper and called dubbed it "ACE".  

​

Bernard gained notoriety on April 14, 1930 when he and Donald Finke flew two Ford A Model powered Pietenpol Air Campers to  St. Paul Air Field (all grass runways), today known as St. Paul Downtown Airport a.k.a. Holman Field today.  Not only did Bernard want an airplane that was easy to construct, it had to be reasonably easy to fly, since many of those who he envisioned flying his airplane would be, like him, novices when it came to piloting skills. Bernard and Don met with Weston Farmer, editor of Modern Mechanics and Inventions magazine,  proving to the world that a two place Ford Model A powered Pietenpol Air Camper was real! That day aviation history was made! Bernard was officially named the "Father of the homebuilt aircraft".

​

A light version of the Back Story(Quick Guide if you will) ;

 

Bernard was humble and a genius. He would help anyone with any project (much like a very important friend of Bernard's, Forrest Lovley of Jordan, MN.  Forrest Lovley at the young age of 18, shortly after high school graduation flew solo from Minneapolis, Minnesota, to Maine and back in a 1933 Model A-powered Pietenpol Air Camper Bernard built. Forrest today is 83+ years old. Forrest has plaqe on the wall of EAA's Hall of Fame. As Bernard's grandson Andrew Pietenpol, I hold Bernard and Forrest as the best role models a man or woman could ever have. They are certinly mine! Ok, I am biased.  Bernard Pietenpol I hold above all people!  But God comes first.

 

​​From the beginning, Bernard showed an aptitude for all things mechanical and became the town's "mechanical genius", building a car from an old tractor, small engine powered wheel chair to assist the handicap, as well as a gas-powered generator to generate power long before Cherry Grove had commercial electric power installation 1938. Like many mechanically inclined young men of his generation, Bernard  fixed and traded Indian motorcylcles and all makes of automobiles.  Bernard's two friends Don Finke and Orin Hoopman began experimenting with various wing and fuselage designs long before the April 14th, 1930 meeting with West Farmer. There were lots of  trial and error for Bernard in search for the correct combination, always keeping mind that he wanted to develop an airplane that anyone could afford, construct without and enjoy without the large expense of factory-supplied aircraft  parts avoiding complex construction methods. Shortly after Bernard together with the help of his father-in-law William Krueger of Preston, Minnesota milled wood for the first Pietenpol Air Camper wooden kit. Bernard supplied every other part of the Pietenpol Air Camper for sale.  Or you could have a complete plane built for $750.00. Then came WWII, and soon Pietenpol Aircraft Company ground to a hault.  My grandfather told me that Forrest Lovley personally saved the Pietenpol Aircraft Company!

​

His first attempt at a commercial aircraft was to by plans for a Lincoln Sport Biplane from a popular magazine called Modern Mechanics and Inventions Flying Manual published by Fawcett and whose popular aviation writer, E. Weston "Westy" Farmer, was influential in covering the world of "homebuilt aircraft." By now it was the late 1920s and successful designs like Edward Heath's Parasol and O.C. Corben's Baby Ace were being built both as finished aircraft and in kit form by their companies, and plans were being sold to those confident in their abilities as craftsmen. But these designs required some complex construction skills and equipment to manufacture welds or fabricate intricate control mechanisms that were beyond the scope of the average builder. Of course, these parts could be purchased separately by mail, a practice Bernard eventually offered for his own designs as well. But the Heath and Corben models also mainly recommended aircraft powerplants which were less available and much more expensive (though each manufacturer did offer plans for using motorcycle engines). Unlike the Pietenpol Air Camper, experimental aircraft designers thought that automobile engines were simply too underpowered. Aviation was still in its infancy in America.

​

It was also about this time that a young man named Lindbergh flew alone across the Atlantic Ocean in May 21, 1927 inspiring a whole new awakening to the fun, adventure, and romance of aviation.

​

​​​​​​Bernard Pietenpol moved his workshop into an abandoned Lutheran church in Cherry Grove, MN and worked tirelessly.

​

By now Henry Ford had come out with his new car, the Model A, powered by a bigger four cylinder engine. At an estimated 40 horsepower, this engine seemed just the thing for Bernard Pietenpol's new aircraft design's needs, and having been on the market for several years, junk yards were starting to get as many of them as Model T engines.

​

So Bernard Pietenpol went to work converting the Ford Model A engine for his new monoplane. In May 1929 Bernard Pietenpol test flew his Air Camper with the new engine. It was a complete success - a perfect match of airframe to power plant. Conversion of the Model A engine was a bit more extensive than had been necessary for the Model T, but Bernard included extensive and clear instructions in his building manual, also offering parts for sale to those builders who did not have the skills or equipment to make the conversions such as aftermarket magnetos, shorter water pump, carburetor heat piping, and exhaust stacks. Or, a buyer could purchase a "ready-to-fly" Model A powered Air Camper for $750.

​

Bernard Pietenpol's big break occurred in 1930 when aviation editor "Westy" Farmer attended a fly-in at Minneapolis. In previous columns in Modern Mechanics and Inventions Flying Manual, Farmer had declared that he was not a big fan of using automotive engines in aircraft and specifically said that Ford's Model A engine was not usable at all. Pietenpol decided to make the flight in his Air Camper up to Minneapolis to prove the editor wrong. In fact he had Finke fly a second Model A powered airship to the fly-in. Once face-to-face with Farmer, Pietenpol told the crowd, "I believe that this is the safest plane for the beginner that has ever been built." He made such an impression on Farmer, and the rest of the crowd, that Modern Mechanics and Inventions Flying Manual published his Air Camper plans serialized in four 1931 issues. That really put Bernard Pietenpol, the Air Camper, and Cherry Grove on the aviation map. Letters arrived in bunches.

​

Bernard Pietenpol offered fatherly advice to his customers. For example: "If you realize that you are not capable of building a good ship, then do not try. Either buy a ship or have someone build it for you that can. Don't build an unsafe ship."

​

He also had his views about aircraft safety when it came to flying. "I do not believe in stunting, it is the cause of nearly all accidents. I believe in safe and sane flying only. My advice is, do not stunt much or take unnecessary chances."

​

Unlike some of his fellow homebuilt pioneers, Bernard Pietenpol actually built very few airplanes at his Minnesota airfield/worksite, perhaps only 23. Like aircraft designer Burton Rutan decades later, Bernard Pietenpol made more of a business of providing plans for his designs. During the 1930's, he sold thousands of sets of plans to eager builders all over the country as well as many overseas. Assembly kits were also available and he sold hundreds of them, along with his availability as a friendly personal "consultant" to any builder's question, no matter how small. For example: "There is no point in using a lot of nails. The strength lies in the gusset plate and gluing."

​

Meanwhile, Bernard Pietenpol continued working on improving the Air Camper's design. Comming out with the lastest most improved  improved verion, which, at under 600 pounds. Orrin Hoopman not only drew all the plans for the Air Camper and Sky Scout, but also given the first Sky Scout built in exchange for good will. With a top speed of 62 mph and cruise of 55, the new single seater could take off in about 150 feet and land in 250 ft..

​

Both the Air Camper and Sky Scout plans were published in the  Modern Mechanics and Inventions Flying Manual. Pietenpol Air Camper's and Sky Scout's drew great crowds at fly-ins. Always the enthusiastic promoter of flying for everyone, Bernard Pietenpol offered rides to the public in nearby communities on Sunday afternoons, insisting that all his pilots wear white shirts and ties. Bernard said, " I built the Air Camper to prove to myself that I could build a ship powered with a motor which would be practical, and also prove that the Model A engine automobile motor would fly successfully."

​

Bernard Pietenpol kept experimenting with new powerplants. He even beefed up the Air Camper's wing area on one model in order to handle the added weight of a V-8 engine. At 80 horsepower, the performance was better than the Model A, but the fuel consumption was also twice as high. He also tried a 60 horsepower Franklin aircraft engine, which was a fair powerplant. By then there were also aluminum cylinder heads available for the Model A which Pietenpol tried and enthusiastically recommended to customers as a relatively inexpensive upgrade. He never stopped looking for ways to improve his airplanes' performance.

​

As the years passed, Bernard Pietenpol taught himself how to repair televisions and radios. By 1960, Chevrolet introduced the six cylinder air-cooled Chevrolet Corvair. This would be the last engine Bernard would experiment with in powering his Air Camper. In 1966 Bernard completed his first Corvair powered Air Camper, then another in 1970 which was dubbed "the Last Original". By then, plans for Pietenpol's have been sold all over the world including Canada, England, Europe, Australia, and Africa.

​

As time went by, the aviation world recognized all the contributions that Bernard Pietenpol had made not just to the homebuilt aircraft industry, but to aviation in general. In 1991 (seven years after his death), Pietenpol was inducted into Minnesota's Aviation Hall of Fame, and is today nationally recognized as "The Father of the Homebuilt Aircraft".

​

Eventually, the two original hangars at Pietenpol's field at Cherry Grove, Minnesota, were moved to other historic preservation sites: one to the Fillmore County Historical Center in Fountain, MN and the other to the Experimental Aircraft Association's Whittman Field at Oshkosh, Wisconsin. Today the Pietenpol legacy continues as Bernard Pietenpol's grandson, Andrew Pietenpol, continues to provide Pietenpol Air Camper and Sky Scout blueprints, builders manuals, aircraft kit sales, and technical support to enthusiasts who want to try their hand in building one.

"Nothing happens unless first a dream." Bernard Pietenpol's dream continues, and inspires a whole new generation to dream, too.

​

Special Note: For a time Andrew Pietenpol flew the last Air Camper Bernard Pietenpol ever built (NX899H). Today Andrew Pietenpol has renovated the Bernard Pietenpol Cherry Grove Pietenpol Field & Workshop. Andrew continues following in the foot path of his grandfather Bernard Pietenpol building and flying Air Campers on the same 1400' airstrip. The Pietenpol Family has come full circle with Andrew Pietenpol proudly paralleling the life of his admired grandfather Bernard Pietenpol.

(Thoughts from Bernard Pietenpol's grandson Andrew Pietenpol regarding his grandfather's philosophy)

​

His philosophy was he wanted to design an airplane out of common parts that a common man could afford and build. You made good with what you had, and if you didn't have it, you made it, and that's essentially what he did with his airplanes.

​

Thoughts from Andrew Pietenpol
A Pietenpol Air Camper is a plane my grandfather Bernard H. Pietenpol designed. It is more of a memory than it is a plane for me. Bernard passed away when I was in college in 1984. Bernard gave a lot of people enjoyment! He gave a lot of rides, and people got to experience their first airplane ride through his generosity. He would many times after church on Sundays give free rides. People from all over the community would show up at his airstrip in Cherry Grove, Minnesota. Bernard would load people in and out of his Air Camper flying them up - around - and then down. He did this over and over for his entire life. Some of those people were inspired to become pilots and build their own plane. I'm lucky to have had the opportunity to learn from my father and grandfather. Life is a full circle and it's just coming back around.

​

Thoughts from Donald Pietenpol (Bernard's Son)
I grew up looking out our window looking into the yard and seeing an airplane my dad had built. I was around airplanes since I was 3 years old and thinking nothing of it.

​

Thoughts from Andrew Pietenpol
He'd leave a plane out in the front in case someone had to go to the hospital.

​

Thoughts from Donald Pietenpol
If somebody got sick in Cherry Grove and there's 12 miles of snow, my dad would go in the shop and pour hot oil on the engine, hot Prestone in the radiator, start the engine and fly them to the doctor.

​

Thoughts from Andrew Pietenpol
I can't tell you how many times a person has come up to me in Fillmore County and said I got my first ride in a plane with your grandfather and it was just wonderful!

​

Thoughts from Donald Pietenpol
I've asked my father sometimes in years past, how did you know how to do this? How did you know how to build an airplane? And his answer to me was always the same. I always knew how.

​

Thoughts from Andrew Pietenpol
Bernard had to teach himself how to fly.  

​

Thoughts from Donald Pietenpol
He didn't study. He didn't go to school for it. He didn't buy books for it. He just sat down with a piece of paper. All of these things are hand done, hand built. All put together and they all fit. It's just one of those phenomenal things that happened, 

​

Thoughts from Andrew Pietenpol
He just got out there, made the mistakes, and if he messed something up he fixed it and eventually figured it out.

​

Thoughts from Donald Pietenpol
My dad said; "I found out that if I wanted to make the nose of the airplane to go down I could stick both hands and arms out and the nose would go over. If I wanted to climb I found out I could take my helmet off and put it over the over the trailing edge of the airplane and the airplane would climb". My dad said; "I didn't know how to fly, but my airplanes did". Back in the 1930's factory built aircraft were very expensive and people had no money. Owning and flying your own airplane was totally beyond anyone's dream back in the thirties. Then came out an airplane that somebody could build themselves with parts obtained just by going down to the hardware store. That's just what we needed back in the depression years. And he actually took a piece of black walnut out of a log and whittled a propeller out of it.

​

Thoughts from Donald Pietenpol
Back then (1932) the editor of Modern Mechanics magazine made a statement that an airplane couldn't fly with an automobile engine. So my dad wrote him a letter. And he says automobile engines do fly, in fact I have two of them flying right now. When the editor wrote back he says O.K., prove it. Fly em up here, I want to see em. So they flew two airplanes up there and the editor of Popular Mechanics was so impressed he said draw the plans - I'll publish it. So that started the whole series in Modern Mechanics magazine. That was the beginning of it. And the plans were seven dollars and fifty cents. I know before WWII that he had sent out over six thousand sets of plans.

​

Thoughts from Andrew Pietenpol
During WWII, Bernard Pietenpol ended up in the civilian pilot training program. With his knowledge of airplanes, he taught young pilots basic flight lessons and how to fix planes.

​

Thoughts from Donald Pietenpol
So he spent his years, the war years down there. Patriotism was a little different then. Everybody wanted a job that did something to shorten the war, to do a good job for the country. That was part of the backbone of the people in those days. It runs in the genes, I'm certain it does! My dad flew, my brother flew in WWII, I fly, my son flies. (Three generations of Flying Pietenpol pilots - sort of cool!)

​

Thoughts from Andrew Pietenpol
As a kid I grew up here on Pietenpol Field spending lots of time with my grandfather Bernard Pietenpol. Together we would build airplane parts for my future Air Camper. Mostly Air Camper ribs. Today I have fond memories.  I have since 4 years of age. Communicated to everyone that would listen to me including resident pocket gophers, mice, snakes, and toads that I would return to my grandfather's field and honor my grandfather Bernard Pietenpol. My carrying on what was started over 98 years ago. I have built on "Pietenpol Field" an airplane hangar, and a house that is of the same exact size and footprint as the original hangar and house. Happily I can say today I use "Pietenpol Field" just like Bernard and Don did building Air Campers, flying planes, and best of all doing what I do best "putz around" (I am a putzer first and foremost on all things mechanical, electrical, or computer powered). Cutting lots of airstrip grass, trapping those pesky pocket gophers is also a carryover experience that is hard work, but worth all those hours of loving labor.

​

Thoughts from Andrew Pietenpol
The fly-in at Brodhead, WI happens once a year. It is a bunch of Pietenpol enthusiasts! It's a great opportunity for everybody to compare notes as to how they built their airplane. Every Pietenpol here is different. Everybody puts his or her own signature on the airplane when they build it. It's a plans built airplane. And we have a saying here at Brodhead. That the people come here for the first time to see the airplanes, and they come back because of the people. It's a pretty good size gathering. You don't see these people walking around with a glum look on their face. They've got something that really gets their attention. They come from all over the country here to find out how to build a Pietenpol. If you have a genuine interest in Pietenpol Aircraft I would suggest you join the Brodhead Pietenpol Association.  The Brodhead Pietenpol Association is a "Type-Club" for owners, pilots, builders, and simply aficionados of the ubiquitous Pietenpol aircraft design. I have included a link to this fine organization.  Please feel free to visit and learn more about Pietenpol Aircraft! Please click on the following link >>> Brodhead Pietenpol Association <<<
