Restoration Continued

It has been several years since I endeavored to help my dad finish his Porterfield.  Shortly after we started, I relocated to Montana.  Now I'm back in Ohio and determined to finish this project.  He and I began in earnest a few weeks ago.  This time we have help from a couple of friends, one who's an A&P and another who's an IA.

To quickly give everyone an idea of where we stand on the project, the wings and engine have been rebuilt and the fuselage has been repainted. …

Porterfield Club Newsletters


I have within my fathers paperwork / files a number of Porterfield Club Newsletters. Would current club members be interested in a project to have these inventoried, scanned into searchable PDFs, and either posted to the club site or made available to club members? Any and all thoughts on this would be appreciated.

A Tribute to My Dad

Today is July 10th, 2020. My mother and father would have been married for 80 years today. They have long since passed, but I am still amazed by their lives. Happy anniversary Mom and Dad.

Since my dad was so involved with the Porterfield aircraft, I wanted to re-share a bio that appeared in the Porterfield Club newsletter in April of 1978. It was authored by Chuck LeBrecht with inputs from my dad.

There are some errors, spelling, grammatical, and factual (I…

need fairleads for 1940 Collegiate

I am restoring a 1940 Collegiate and need to find a source for control cable fairleads. The fairleads are .550 in diameter and 1" long. I have checked all the traditional sources and they all have Piper cub fairleads that are .750" in diameter. Does anyone have a source for Porterfield fairleads?

Replacing Bendix SF4-RN8 mags with SLICK 4333

Has anyone preplaced the old Bendix SF4 mags on their CP-65 with SLICK 4333 mags?

It appears that spacers are required between the accessory case and mag to accommodate the required impulse coupler. I welcome any and all information or comments on the conversion process and parts required.

Are there any Collegiates in Michigan?

I have a 1940 Porterfield basket case that I am restoring. I have very little technical information to put this thing back together. I've done OK so far, but could use some pictures of one that is together and flying. I built new wings and am ready to cover them. Progress has been slow as I put the pieces of the puzzle together. 

Please call me if you have one that I could come and take pictures of inside and out. I do not want to disassemble anything or cause any harm in doing so.…

Need fuselage drawing for LP/CP65

Fellow club members: I have engaged a vintage DAR. To assist with the engineering analysis for a C85 conversion for the 65 Porterfield. I need the fuselage drawings to help get the analysis going.  My DAR has contacted the Rankins and they will try to help, but their drawings are still boxed up and things are difficult to find. If anyone has the drawings I would be very interested in getting a copy.  Please help if you can. I am certainly willing to pay for copies.  The analysis will not be…

Question about Headknockers - aileron balance weights

I have a 1940 CP50 that I am restoring from the ground up.  I  built new ailerons and transferred the lead weight from the old aileron to the leading edge spar of the new aileron.  While in Osh Kosh I saw a LP65 with headknockers for balance weights. My CP50 was not equipped with headknockers. I searched for AD's but could not find any for the CP50. Does anyone know if the headknockers was an STC or some other add-on? My ailerons are quite heavy at the trailing edge. I have always been told…

G-AFZL in the wars again

ZL suffered another nose over incident at the end of August. This time it was Paul, he forgot to reset the throttle starting the engine after blowing out, resulting in the engine revving up at the next swing and the aircraft nosing over the chocks. Luckily the prop missed Paul, but buried itself in the grass. We sent the engine away for a shockload examination and fitted a new prop. No other damage luckily and she's now signed off again, although the weather has turned damp and cloudy, so…
