Default Cherokee Tri-motor

I looked around i think it was called an XPA-32 and was the precursor to the PA-32, dont think any pictures exist.

N8461R & N8438R were 140's operated by the Bergstrom AFB Aero Club.

One of them received an outboard engine from the "Piper Tri-motor".

I've been looking ever since then.

Bart, a picture from my Piper book:



Designated the PA-32-3M and registered N9999W, the aircraft was "a quick rebuild of the original prototype Cherokee Six and was a non-conformity aircraft." The airplane's wings were fitted with two 115 hp Lycoming O-235 engines in pseudo Twinkie nacelles in addition to the 250hp Lycoming O-360 in the nose. The fuel tanks were removed from the wing and the wing structure beefed up. Tip tanks fed the two wing engines while a Pawnee fuel tank mounted in the cabin fed the larger Lyc. The two 115 hp engines proved anemic during engine-out tests and were beefed up to 150 hp. However, with the fixed-pitch props, the engine-out characteristics were too great and unwilling to put constant-speed propellers on, Piper cancelled the project.

Raptor

Would you provide the title & possibly the ISBN for your "Piper Book"?

Thanks

Wow, with such genius running the company it's a wonder Piper survived back then. That has to be about as goofy an idea as I've ever heard of relating to GA.

Leigh,

I know this is a year late for a reply....

I was delivering a plane from Piper in the late 60s, stuck my head in a hangar...saw a Tri Motor Cherokee Six, and was promptly asked to leave.

A couple of years later I delivered a few of the first Senecas. The Tri motor was just a proof of concept test bed for the Seneca. ( as I remember) I don't believe they ever intended to produce it with three engines.

Jeff is right, it was strictly a test bed. Nothing goofy about it.
