Rear Strut Fork Fitting For Colligiate

Hello all. Does anyone know if the rear wing strut adjustment fork was "generic" to any other aircraft from that era? Or (an astronomical long shot here..) happen to have one or two that are…Continue

Rear Strut Fork Fitting For Colligiate

Hello all. Does anyone know if the rear wing strut adjustment fork was "generic" to any other aircraft from that era? Or (an astronomical long shot here..) happen to have one or two that are serviceable available? Oneof mine has some surface corrosion that is making the IA a bit nervous. See attached photo.  Thanks, Mark NC27249See More

"Hi Andy, I’ll go down to the hanger tomorrow and get a photo. Pretty sure it’s original. And yes, there is a different valve for the low point sump. "

"Are you able to take a photo of the valve and post it here, Mark? Over her 80+ years, she may have had the factory installed valve replaced by a non-standard type. Is there a second valve installed down under for draining the fuel tank sump?"

Leaking fuel tank shut off

Hello fellow Skinny birders. My fuel tank shut off valve is leaking past the packing nut. Does anyone know what the correct packing would be to use so I can rebuild it? Maybe it’s a generic packing that’s fuel proof. But thought I’d put it out there and see if anybody else has done this before.Thanks,MarkSee More

"That’s a fantastic find Mark! I have one but the angle drive wore out. I found a Stewart Warner at Oshkosh and hoping my local instrument people can make 1 out of the 2. (P.S. I’m from down under Australia)"

Porterfield Tachometer

I found this old tachometer at a fly in at Hood River back in September. I sent it off to Air Parts of Lock Haven for restoration. They did an absolutely beautiful job! I would recommend them to anyone for instrument overhaul. Not sure what else they do, but I believe they offer other services as well. I had no idea there were instruments that had the Porterfield name on the face plate like Piper did with the Cubs. Anybody out there seen this before?See More

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
