Hey guys, in another topic I mentioned that I had found the FAA database for TCDS's on the web and it listed if the certificate was held in the public domain.
Well I was looking at the certificates and was pleasantly surprised to find out that the Stinson SM8A certificate is now a public document.
That aircraft was powered by a Lycoming R680 rated at 215 horsepower. Anybody have any idea as to how common are these engines out on the used market? And if they are rare, anybody have a recommendation for an acceptable modern substitute that may have the potental to be used in it's place?
