Welcome

I don't know if any of you were a member of the "Porterfield Airplane Club" which Chuck Lebrecht hosted for many years. Chuck has decided to give up the Porterfield Club due to health and economic reasons. I've taken it upon myself to keep the legacy going and have started this social web site dedicated to "Keeping the Skinny Birds Flying".

The site will be a good place to share information, pictures, stories, videos, parts, and to create lasting friendships for people with an interest or knowledge of the Porterfield Airplane. I just started getting this site together June 1st, 2009, so there is a limited amount of information. If you have any information to add, please do. If you have parts for sale, help items, technical info, or just want to share your airplane pictures please join us.

Also, if you have any ideas to improve the site, please feel free to comment and/or help build the site. I hope that this site will generate a database for information and history pertaining to the Porterfield Airplanes that may be shared and used by all interested. As well as a place to meet and make life long friends whom share some of the same interests of flying, building, and knowledge of the Porterfield Airplane. If you know any others that may be interested please invite them to join.

Brief History of the Porterfield Airplane

The American Eagle Aircraft Corporation was started in 1925 by Ed Porterfield for the express purpose of providing a safe training aircraft for the fledgling Porterfield Flying School. Porterfield felt that a safer, better performing trainer was badly needed to replace the existing "Jennys" and Lincoln "Standards" being used in his flight school. In April 1926, the American Eagle, Model A-1, first flew from Richards Field in Kansas City, Missouri. The airplane had been designed by Waverly Stearman after much consultation with Porterfield concerning the characteristics necessary for a good training aircraft. It was a three-place, open cockpit bi-plane that was suitable for both training and light commercial activity and was typical of the era. In November, 1927, the OX-5 powered A-1 received an Approved type Certificate - ATC #17. Various changes were made to the original A-1 design (The most notable being the addition of ailerons on the lower wing.) leading to the A-101 designation. Most Eagles were powered with war surplus Curtiss OX-5 engines, but variations were available with the OXX-6, Hisso, Anzani, and others. During may of 1928, production was 12 planes per week with ever increasing orders. In mid-1928 an OX-5 powered A-101 sold for $2815. Approximately 300 of the A-1 / A-101 models were sold.

In 1929, American Eagle brought out a new model, the A-129, which received ATC #124. The new model was very similar to the earlier "Eagles" except that it was powered by a 5-cylinder Kinner K5 engine which required a longer nose on the aircraft to maintain proper balance. This gave rise to the "Eagle" A-1 and A-101 versions being called "shortnose Eagles", and the A-129 Kinner powered model being called the "longnose Eagle" and other such names. The A-129 "Kinner Eagle" would not win any beauty contests, but it was stable and reasonably easy to fly. The A-129 was also sold with several other engine configurations including the OX-5 and OXX-6.

During 1928 and 1929 business was booming for the American Eagle Aircraft Corporation and they produced several other aircraft in addition to the A-101 and A-129. None of these sold as well, but production of the A-201, A-139, A-229, A-329, A-429, as well as several prototypes, placed the company near the top of the vibrant aircraft industry. The stockmarket crash in late 1929 changed all that, and in 1930 the company found almost no market for its aircraft. In desperation, Porterfield started the design that eventually became the American Eaglet monoplane. It was a small, light weight, parasol design that was powered by a three cylinder Szekely radial engine. Although the "Eaglet" sold fairly well, the company was in trouble, and in May 1931, the American Eagle Aircraft Corporation merged with the Lincoln Aircraft Company. The new company was known as the American-Eagle-Lincoln Aircraft Company, and most of the production was focused on the "Eaglet". However, the deepening depression soon ended this last gasp of American Eagle. Ed Porterfield went on in later years to organize the well known Porterfield Airplane Company.

During its six years in existence the American Eagle Aircraft Corporation produced over 700 aircraft and held eight Approved Type Certificates issued by the Department of Commerce. It was the third largest producer of commercial aircraft in the world at the time of the depression, and its products were among the finest private aircraft manufactured during that era.

History from Wings of History Museum.


During the 1930s, the firm of Porterfield Aircraft Corporation, located in Kansas City, was enjoying a modest success with the Model 35 light aircraft - a tandem two-seater built of traditional steel tube fuselage with a wooden wing - all, of course, covered in fabric. The exceedingly slim fuselage sported a variety of engines including the five-cylinder Warner Scarab junior radial of 90-hp. Aimed at the lower-cost sport flying market, the Model 35 could be fitted with various options and numerous paint schemes were available.

As the new four-cylinder opposed powerplants came available, Ed Porterfield modified his basic design a bit to take advantage of these new and reliable engines. The CP-50 retained the standard Porterfield profile but it was fitted with either Franklin, Continental, or Lycoming engines - all of 50-hp. Given the name Collegiate, famed race pilot Roscoe Turner was briefly the sales manager and director of advertising for the new design. Available in variants ranging from a very basic training machine to a more deluxe sports model, over 50 were built before attention was turned to the higher-powered CP-55 and CP-65 models.

Once again, these aircraft were all fitted with opposed engines from the three manufacturers but the airframes were basically similar to the earlier design.
Porterfield never achieved the numerical success of the larger light aircraft manufacturers such as Piper, Aeronca, and Taylorcraft but the planes were well made and popular with pilots. However, with the start of World War Two, light aircraft production for civilian use came to a stop and the bigger companies benefited greatly from military contracts but Porterfield, with no large military orders forthcoming, quietly faded away.

High Flight

Oh, I have slipped the surly bonds of earth
And danced the skies on laughter-silvered wings;
Sunward I've climbed, and joined the tumbling mirth
Of sun-split clouds and done a hundred things
You have not dreamed of wheeled and soared and swung
High in the sunlit silence. Hov'ring there,
I've chased the shouting wind along, and flung
My eager craft through footless halls of air.
Up, up the long, delirious burning blue,
I've topped the windswept heights with easy grace
Where never lark, or even eagle flew.
And, while with silent, lifting mind I've trod
The high untresspassed sanctity of space,
Put out my hand, and touched the face of God.

John Gillespie Magee, Jr

Rare LSA Porterfield Makes Second Oshkosh Visit

Rare LSA Porterfield Makes Second Oshkosh Visit

By Randy Dufault

Dave Reichard wasn’t looking for a rare airplane when he began searching for a plane to exercise his newly minted sport pilot certificate in. At the time, an Aeronca Champ seemed like the logical choice since that was his mount for most of his training.

A for-sale listing changed that decision.

“I have a friend who looks at all the antique listings,” Dave said. “He told me one day, ‘Hey Dave, there’s a Porterfield for sale.’ And I said to him the same thing that everyone says to me when I say I have a Porterfield, ‘What’s a Porterfield?’”

A trip to a private airstrip in Kentucky followed, and Dave purchased the plane.

“My friend that told me about it has lots of tailwheel time in lots of different types. A friend who is my mechanic and is an IA and I went down … and we checked it out,” Dave said.

After some back and forth over the paperwork, Dave paid for the craft. Test flights demonstrated it had no bad tendencies and was a sweet-flying airplane.

A 7.3-hour cross-country effort brought the plane here to EAA AirVenture Oshkosh 2017 from its current home in the Dayton, Ohio, area. Eighty mph cruise speeds, and a particularly short range, make such trips a lengthy affair.

Dave last brought the plane to Oshkosh in 2014, shortly after he purchased it.

“In 2014, I met several other Porterfield owners, and one of them told me that there were 24 flying examples in the world,” Dave said. “A fellow I met this past [weekend] has one that’s bent, so there might only be 23 right now.”

“I have not met another Porterfield owner, except online or at AirVenture,” he added. “I’ve not seen another Porterfield [airplane].”

Porterfield built airplanes for a short period before World War II, and this LP65 (Lycoming powered) model was one of its last efforts. A tornado damaged this particular craft in the 1970s, and, according to Dave, it spent nearly 30 years of its 77-year life not flying. Restoration eventually happened, and the completed project appeared in the September 2008 issue of EAA’s Vintage Airplane magazine.

All Porterfield models are compliant, type-certificated light-sport aircraft.

Dave has added about 100 hours, half of his total time as a pilot, to the LP65 since he purchased it. He enjoys bringing it to fly-in events around the Dayton area, and is always ready and willing to answer the “What is it?” question.

“That’s what happens when you own a rare airplane,” Dave said.
