"Bonjour, mon ami: I was looking at your nice Tumblr page and noticed the weight and balance report has three pages, but page 3 is a duplicate of page 2. Is there a page 3 in the original report? Débarquements doux, Andy"

Looking in the FAA database, I see that as of 03/08/2017, Bradley Rankin now owns the type certificate.  He inherited it from his Dad, Joe, who passed away last fall.  He hasn't transferred ownership of the TC's for the earlier Porterfields, yet, so hopefully they won't end up lost in the Twilight Zone.  Brad also took over from his Dad at the family airport just south of Maryville, MO.See More

About Me:
Enough about me, let's talk about you...
Do you own a Porterfield Airplane?
NC41VT, 1941 FP-65, S/N 875 Has a Franklin 90 installed by Angelo Forte, under a one-time STC, in the mid-50's, and has had the seaplane conversion done to it (would that make it a FS-90?). I just need a cheap set of Edo 1320's now!
Are You a Pilot?
Why yes, I fly...

NC41VT and I are now back home in Vermont! How we got here...

I'm sitting in KMHT, writing this while waiting for my flight which should be wheels up in about 10 hours.  I fly to Newark, then to Seattle, then to Great Falls, and should be wheels down at KHLN about midnight (about 31 hours from now).  Hey, I live in New England!  We can't get anywhere from here!  41VT is at Boulder (K3U9) Airport, about 25 miles south of Helena, MT.  I'll buy a used bike  Wednesday morning (I hope), and pedal on down to Boulder to start prepping myself and 41VT for our…

Update on my '41 FP-65 project

After tinkering for over three years on my Collegiate, the novelty finally wore off for Pokey Gordon and he asked me to remove the old girl from his shop in Helena, MT.  Club member Tim Talen, who has a hangar in Boulder, MT, about 30 miles south of Helena, came to the rescue and arranged for a Boulder friend of his to rent a truck and haul the project to his hangar. 

Tim's is a master restorer who specializes in Interstate Aircraft.  I restored an Interstate Cadet back in the 80's…

LeRoy was more than generous with his time. I hope I remember a good portion of the information he's shared. I spent two days up there and almost countless phone calls. I have a hanger and feel a privilege and responsibility more than ownership. I have a daughter in Brooklyn so there's a good chance we could meet in the next year.

Im interested in the historic role of the Porterfeld as chase plane and filming platform for the 1st manned rocket flight (Ercoupe) at March Air Field in September 1941.

The pilot who made the flight was a good friend, Captain Homer Boushey who at the time worked at Wright Field. Would value any information from anyone as to exact model of Porterfield, engine type, manuals for the type, prop, markings et al. 

I would like to find a Porterfield with the exact specs. as the one used (there is footage showing it) to purchase and re-enact this historic event.  If your club owner/operators could educate me on that exact model that would be fantastic.

Thank you all for keeping aviation history alive.

All the best-

Bradley

The encoder is actually remote from the radio panel, I made a "trap door" in the right side cabin wall just below the upper longeron and just behind the instrument panel. The encoder is mounted on the back side of the trapdoor. The altimeter, airspeed and encoder static ports a r connected together and vented behind the instrument panel through a .032 dia. orifice to reduce "gauge flutter" The wiring connections between the encoder and TXPDR are routed up the right side rear edge of the windshield just ahead of the door frame.

FYI, I recall recently seeing an ad by Microair for a low power consumption TXPDR, that would be worth investigating if you a re planning to use total loss battery power system.
Let me know if there's anything more I can help out with

Andy, Yes the wheel pants on my CP-65 are original. I'm extremely fortunate to have picked-up a Porterfield that has been restored to, what I believe, is as close to original as you can get. Fred Hollaway is the gentleman that did the restoration in the late 70's. To give you an idea of the detail Fred went to, he braided all of the control cables in the original fashion with a waxed cotton twine wrap. Just one example of many that make NC37895 very special. She fly's like a dream as well.

Well, it's got a big tail but a C90-12F so it's got a starter and a generator. Yeah, no more propping for me!

My craft is registered in Mexico, since they absolutely require comm. and XPDR I simply added them with out saying anything to anybody. I chose Microair 720 ch comm. and XPDR / King encoder as they were the lightest smallest lowest powered combination I could find as of 3yrs ago. Power is supplied via 7 amp hr sealed lead acid battery mounted on the cabin side of fus station #1. Everything works well with good TX/RX and virtually no engine ignition noise. Ingntion system is shielded type.

The installation required modification to the right wing root to pass the equipment through from the cabin. In the U.S. this of course would require an STC or onetime field approval, the Mexican DGAC (equiv to FAA) never thought to ask so I didn't tell, if they had it would have been impossible as they would have required Porterfield factory engineering approval, so you see where that would have gone! If your interested I can send you some photos of the istallation and a wiring diagram. Before retiring I was an electronics engineer for 32 years.

Andy,
I think that would be Kent Pramhus' Little Blue and Silver Porterfield. It is a beautiful airplane. He was one of the first members here. It is at Cable Airport in California. There are 3 Porterfields at that airport. I think the airport has a web site, I think it is www.cableairport.com and also www.foothillaircraft.com
There are pictures of it under used aircraft on the Foot Hill site.

Welcome to our Porterfield Club. We are glad to have you join us. Hope we can all benefit each other with technical info on the Porterfields and build lasting friendships. We look forward to pictures of you and your airplane.
