Cont. A-40 or A-50?
I'm curious if anyone can comment on what the parts availability for
these two engines is. Are they becoming too rare to maintain adequetely? Anyone have any experience flying behind one? I saw a Heath Parasol at OSH that had an A-40 and a Porterfield with an A-50, and I recently picked up the book: "Flying with 40 Horses" by Chet Peek and was curious if anyone out there still flies with these engine, or have they all gone with C-65's? Thanks, Ryan in Madison |

There's a good few still flying of both types. With all engines of this vintage you have to get a bit creative with parts, though. Things like rings and valves can usually be gotten from some other engine or if they're only close, then modified to fit. For instance, there's a Ford tractor ring that fits the a-50 perfectly. It's not a certified part, but it is exactly the same ring that the manual calls for, just without a tag. Mags and carbs can be dealt with easily and there's not a lot else to the things anyway. You'll end up with a garage full of parts engines if you're smart, though. Look at it this way, a lot of OX-5s are still flying. It's all do-able as long as you're dedicated and not afraid of the work and $$$. Bertie |

Bertie,
Thanks for the reply. What have you worked on/flown/owned that had one of these engines? I'm curious the particular aircraft that people have had experience on/with. Is the A-50 dual ignition? Can one use a non-certified part (like a ford tractor ring) on a plane with an ATC? Or is it a matter of don't ask, don't tell? I'm not an A&P, so I'm coming at this from the perspective of an enthusiast pilot, who doesn't necessarily know what the devil is in the details (yet...). Thanks again. Ryan |

oups.com: Bertie, Thanks for the reply. What have you worked on/flown/owned that had one of these engines? I'm curious the particular aircraft that people have had experience on/with. I've flown a J-2 and owned an early Luscombe 8. Flew a chief with an a- 50 once as well. Is the A-50 dual ignition? Some are some aren't. I'm not sure of the designation differences, though or if it was converted after or what the story is there. Can one use a non-certified part (like a ford tractor ring) on a plane with an ATC? Or is it a matter of don't ask, don't tell? Uh, bit of both, really. I have a Le Blond at the moment an Le Blond owners are using all sorts of stuff on their engines to keep them going. Valve springs in particular are like hen's teeth, but there's a guy who's remanufacturing them now. Up til then people were using O-200 springs. It's all done pretty openly, basically because there's no other way to keep the things running.By the way, the tractor rings are actually the same rings, just not certified. same TRW part number, just no tags. I'm not an A&P, so I'm coming at this from the perspective of an enthusiast pilot, who doesn't necessarily know what the devil is in the details (yet...). I'm not one either, but if you can work on a lawnmower you can keep an a-40 going. Just for instance, if it's running rich, you take the carb apart and bend the float valve arm down about 1/16th of an inch at the end and then try again... They're pretty agricultural. Don't get the idea I'm expert with these things. Place you want to ask is rec.aviation.homebuilt. There're people there that could strip either one of those engines blindfolded. Bertie |

Is there a TBO for the A-40 or A-50?
I've been trolling around the internet, and can't find a whole lot of background info on the engines in contemporary use today. Thanks for the responses! -Ryan |

Ryan, you might check a Continental parts catalog. I think I was told that many of the O-200 parts will work or have the same part number as the old A-65's. |
