"That’s a good question for Brad Rankin! Most of our old girls have pretty checkered histories of pampering, neglect, and being put to work teaching students how to fly. Some have been in the same family since they flew out of Kansas City."

Joe Rankin

Hello, while going through the owner history of our Porterfield NC 27249, I see that it was owned for a brief period in 1956 by John W Rankin of New Castle Delaware. It made me curious as to whether he was related to Joe Rankin the owner of the type certificate. It’s amazing to me how many owners there were over the years of our bird. At one point in 1944 it was on by the Defense Plant Corporation Washington DC.See More

This is my wife’s grandfather and his friend in 1940 or 41 with our Porterfield. Her grandfather is the tall cool looking dude on the left.

Profile Information

About Me:
My wife and I are the proud owners and caretakers NC27249, #738, a 1940 LP65 (with a Continental 65). This airplane was purchased new by my wife’s grandfather who owned it until about the time the war started. My wife’s father was able to reacquire it in the early 90s in need of restoration. It sat for many years, and was finally restored to pristine conditions in 2015. It’s so cool that my wife and I both get to fly her grandfathers airplane.

LP 65 hub caps

Hello, I've heard that L5 Hub caps will work on the Porterfield. Anybody have any ideas of others that might? I think they would look sharp on our old girl. Thanks Mark NC27249

Landing Gear Rubber

I recently replaced the landing gear rubber on our 1940 LP65. The old ones were cracked and sagging and in dire need of replacement. I talked with Leroy Blum about this via the telephone, and he was very informative. I acquired the rubber stock from L.A. Rubber at a reasonable cost. On this website, I found a link to a photo of the original blueprint showing the proper dimensions (diameter, square hole size, and radius of corners) Near our airport, Arlington Municipal (AWO), I found an… Continue
