PFM on Barnstormers

[triple8s]

Cool pice of Mooney history forsale on barnstormers.

Great plane, if only you could install an IO540.

So...... Don't want to steer a thread into the ditch but why the big Lyc instead of the big TCM ? 

 

[Guest]

A parallel valve 540 is more reliable an IO550, and can be overhauled for not much more than an IO360.

It's a crying shame that Porsche opted out of the aviation engine business. They could have been a fantastic competitor to the duopoly that we are enslaved to.

[Alan Fox]

This is a parts plane , the engine is AD'd out of service , No STC to replace the engine , Not enough of em left to justify creating an STC , and the parts firewall forward are worthless...If I bought one of these new , I would have gone on a tri state killing spree !!!

If parts aren't made or available firewall forward can they be made or taken from an automotive source.  They do it for older planes, warbirds, etc. all the time when parts aren't available.  Just curious?  I met a pilot a few years ago at Big Bear that had a Porsche Mooney.  Porsche payed for the whole TCM conversion.  He said he was way happier with the Porsche motor and wish he could have kept it that way.  It sure is cool looking.  I think it would make a cool show piece for fly inn's.  If your rich enough it seems like it could be done.  It would also make a great museum piece (maybe even in a Porsche dealers show room). It would bring me into a Porsche dealership.   I would love to see one.

I'll always wonder what could have been...I still love the engine gauges and the overall look of the plane.

Too bad it was heavier and slower than a J...

Only good thing is the development of the long body fuselage that turned into the M shortly thereafter. (And then the R, S, and TN)

I was 12 hours from buying one that had the conversion to the big water cooled engine (my TLS came on the market over night) Might have been a mistake but it sure was a sweet flying and COOL looking bird ! The same one was recently for sale again, maybe last year. I can't even recall the conversion name now.....there was a line of twins that had the same engine conversion. Had the big air outlet on the side, think turbine looking :-)

Edit, duh. It was a liquid cooled Rocket Engineering conversion.  This is the one I flew..SWEET !!

Look at those small air inlets. NO shock cooling either, full throttle to the pattern and chop the throttle.

That was the liquid rocket with the 350 hp engine. Monster!

So it's not legal to fly now ?

[N601RX]

The valve springs have an AD that require replacement every 500 hrs and the parts are not available. 

[triple8s]

Not that I would do it, but what is the rule on owner manufactured parts when it comes to powerplant stuff. Valve train items would be the very last thing I'd ever want to monkey with but legally speaking if a part is not available from the manufacturer is there no way to legally keep an aircraft flyable if the manufacturer stops producing the parts needed??

Can someone buy it, put a aircraft engine in it and call it an experimental?

I thought that there was some kind of process to allow orphaned airplanes to keep flying.  ....are you not allowed to put a "suitable substitute" (350hp) engine into your orphaned PFM?

None of the PFM factory engines were ever rated anywhere near 350HP. IIRC the most powerful version was still less than 250hp. It seems to me you could convert to experimental and put whatever you wanted on it. That's process in and of itself would be a challenge. I don't now how you'd observe the "51% rule" with a factory aircraft that's still intact.

Many Warbirds have gone this route, but a great deal of them are a combo of used and owner produced parts built around a data plate.

It would be experimental but not amateur-built. It would be restricted to flight testing, marketing at air shows, etc. you couldn't easily use it to fly to grandma's for thanksgiving.

Grandma wants to fly in a 350hp liquid cooled PFM.

Seriously though - I thought there is some kind of rule that allows for orphaned airplanes to keep flying with "in kind" or suitable replacement parts - and perhaps that can extend to an engine, where the closest in kind engine that can be found would be a continental?  And I am speaking while still keeping it in normal category.

[Andy95W]

A one-time STC (kind of like a field approval) would make it legal.  Not impossible, but not easy either.

I believe that both T6s on my field are experimental. I see those things flying all of the time.

[KSMooniac]

Maintenance and proficiency flights are allowed, and there is a grey area there. If I had a T6 I'd be content doing flights like that for fun, but with a Mooney it is a different story. If I couldn't travel on a whim in a Mooney, I wouldn't want to have it.

Changing engines would definitely fall into the major alteration territory, meaning an STC or field approval would be required. Quite different than substituting a new oil pressure gauge to replace an orphaned one, for example.
