Stinson Model O Replica Project

Posted in Members | April 29, 2008

Brad Poling wrote in about a Stinson Model O replica project:

We are now underway with building a full size replica of the Stinson Model "O". Thirteen Model O's were built during the '30s, and to the best of our knowledge none are known to be in existence today. Plans do not exist, so we are developing our own using photos, and a set of 1/4 scale R.C. model plans.

Much of the Original Model "O" was developed using components from the Stinson SR-5. We are following the same path. We have acquired a Stinson SR-5, and are now in the proscess of converting the components into Model "O" parts.

The basic SR-5 fuselage truss will not be used in our project. It is in good condition, and is up for sale at this time. Many other components and parts are also available. If you are interested, contact us.

We continue to be in search of pictures, and drawings of the "O". Most needed are interior cockpit photos. We, of course would love to hear from anyone who has flown or been associated with her in an any way. The "O" was last known to be in the Los Angeles area in the late "40"s. Twelve of the "O"s went overseas, and no trace has been found of them.

John Crittenden sent us photos of the Porterfield Fly-In that took place at Cable Airport in Los Angeles during March. The bright green aircraft is John's model 35-70 "Spinach":

Stearman M-2 Project

Posted in Members | April 29, 2008

Alan Lopez sent us an update on the Stearman M-2 project being restored by the Posey Brothers in New Jersey:

Mike Posey seems to think that the M-2 will fly sometime this summer. There is much left to do, including fabrication of an exhaust system. I'll certainly bring it to Blakesburg, but I don't know if it will be this year. We'll see...

Happy Flying,

Pink Aeronca L-16!

Posted in Members, Research | April 29, 2008

Here is Elaine Huf's (M-20377-A) Aeronca L-16 from Kingsley, PA which has just recently been returned to flying status. Elaine says:

"It was my choice of color, but when I told Tom I've wanted pink since I first flew this bird in 1976 he couldn't wait to paint it. The logs for this L-16 go back to the early 1950's and they named it Rudolph, there are entries in the logs 'brakes repaird on Rudolph', 'Rudolph in for oil change', etc. How cool is that?"

Looking for lightweight electrical power for your radial?

Posted in News, Members | April 29, 2008

Forest Lovley sent us this article about a lightweight alternator setup:

B & C puts out an 8 amp alternator for the vacuum pump pad on a Lycoming. I came up with what Johnny Cash used to call an "A-dapta-kit" to put the same alternator on a step-up drive for a 220 Continental, or any other radial that has the standard SAE 5 generator mount pad. It's not approved, but I already have a field approval for putting it on the 220 in my QDC. The whole thing weighs 3 pounds installed. If anyone has an interest they can contact me at or phone 952-492-2064 or 952-492-6126.

Mystery Airplane Identified

Posted in Research | April 29, 2008

Gerald Farell wrote to say that he's identified the mystery aircraft photo previously posted here:

Engineer William Waterhouse (from Ryan Aircraft) designed this aircraft to the specifications of the Mexican Air Force. The aircraft was built in Mexico on 1928 by "Compañía Aérea de Construcción y Transportes", also known as "Tijuana Aircraft Co." and named it the "Baja California No. 1" (BC-1).

On 3/8/1928 Luis Farell took off from the Tijuana factory enroute to Mexico City. The temporarly-fitted 185hp BMW IIIa engine quit between Hermosillo and Navajoa, and Farell crash-landed on mountainous terrain. He was uninjured but the BC-1 was destroyed. The BC-2 was fitted with a 220 hp radial Wright J-5C Whirlwind and was flown by Roberto Fierro in a very famous journey across Central and South America.

In-depth Review of new AC 43.13-2B

Posted in News | April 25, 2008

We have begun a more in-depth look/review of AC 43.13-2B and find at present it is not as wide spread in scope as first thought. It is however a definite step in the right direction and being an Advisory Circular it will be easier to amend or add to than an FAR.

At present with exception of Chapter 1 (which I will comment on later in this update) the scope of this document covers a limited number of alterations. The list of alterations covered in this AC include the following;

  1. Communication, Navigation and Emergency Locator Transmitter System Installations
  2. Antenna Installation
  3. Anticollision and supplementary light Installation
  4. Ski Installation
  5. Oxygen System Installations in Non-Pressurized Aircraft
  6. Rotorcraft External-Load-Device Installations, Cargo Slings and External Racks
  7. Glider and Banner Tow-Hitch Installations
  8. Shoulder Harness Installations
  9. Aircraft Battery Installations
  10. Adding or Relocating Instruments
  11. Cargo Tiedown Device Installations

As for Chapter 1, Structural Data, more study is required and will be on going but paragraphs #106 (Materials and Workmanship), #107 (Material Strength, Properties & Design Values), #108 (Fasteners) hold possibilities of being able to use this AC in at least airframe alterations other than what is listed above. At least to some degree but more study is required.

This AC does not appear to provide for alterations in the area of powerplants installation or accessories at this point. Still all in all this is a very positive step on the part of the FAA to recognize that similar alterations in similar type aircraft do not and should not require repetitive and redundant reviews for approval.

AC-43.13B Now Basis Data for Alterations

Posted in News | April 24, 2008

"Thanks" to AAA lifetime member and APM Board member, Mike Lossner, we have just learned of a major change to FAA Advisory Circular AC 43.13. The latest version, AC 43.13-2B dated 3/3/08, contains the following wording under 1. Purpose (emphasis added):

"This AC is for use by mechanics, repair stations, and other certificated entities. This data generally pertains to minor alterations; however, the alteration data herein may be used as approved data for major alterations when the AC chapter, page, and paragraph are listed in block 8 of FAA Form 337 when the user has determined that it is;
  • Appropriate to the product being altered
  • Directly applicable to the alteration being made, and
  • Not contrary to manufacturer's data."

You read that correct. It now appears that the latest version of AC 43.13 can be used not just as a basis for FAA data approval for major repairs but for alterations as well.

We will be studying AC 43.13-2B in greater depth in the next several days but we believe that this change to this document is a step forward by the FAA in helping all antique airplane enthusiasts to "Keep the Antiques Flying"
