RST Engineering wrote: If the valve the person is suggesting that they use is available at the local hardware store, it is far superior to ANYTHING that was available in the middle of the last century. Having done a fair amount of plumbing repairs in the last fifteen years, I beg to differ. Pay *close* attention to the country of manufacture. If the new valve is made in the US, Canada, or just about any European country, Jim's statement is absolutely correct. One made in Indonesia *may* be satisfactory. Having seen the failure rate on the Chinese shutoff valves which I've put in, there's no way I would install something made in Asia in my fuel system. And make absolutely sure that it has the warning label to the effect that it contains substances that are "known to the State of California" to cause birth defects. That substance is lead, which is required in the manufacture of quality brass valves. George Patterson The desire for safety stands against every great and noble enterprise. |

Actually, a crash for any reason is bad if it results in the uncovering of the unapproved part. Matt |

"JDupre5762" wrote in message ... I believe a ball type valve from the local hardware store would do the trick, Quite possibly true but not a legal repair. A look at the FAR indicates replacing the valve is not a major thing and a 337 is not require; however, the proposed valve is not certified for use in an a/c. Look deeper, deeper, deeper into those FARs. Per the FARs Per WHICH FAR? I don't know how many Taylorcrafts have automotive stuff in them. Hell, they were built that way. They have copper plumbing and SAE 45 degree fittings and valves and on and on. The A&P who owned a Taylorcraft used to say, when you were changing out a part, "equal to or better." Now THAT's in the FAR's or somewhere in advisory circulars. I've seen it. I know a Cub with a fuel shutoff valve from Home Depot. It's been there, installed by an A&P, for years. And you know what? It still works. you cannot replace a certificated part with common hardware store parts unless those parts meet whatever standard applies. If you were to replace the fuel shut off valve with something not certificated for that aircraft you would need a Form 337 to gain approval. A 337 doesn't get you approved; that's for major repairs and alterations. You would need to go running to the FSDO for approval first. I plan on talking with the local FSDO, but until then, can someone provide any insight into what I'm going to have to do? Thanks, Mike |

Which he already did, thanks to a simple thing called groups search on
google... Sheesh. "RST Engineering" wrote in message ... Buy what you consider an adequate replacement. Do your homework and get something that will stand up to gasoline for dozens of years. Plug the input and output ports. Put the part into a mixing bowl with sand and dirt. Let the mixer run for a few hours. You now have a part that has been on the airplane for years Nobody is going to question it unless you spill the beans. Sheesh... Jim "Michael Horowitz" wrote in message ... sigh Yeah, and to compound the problem, being in the DC area, the local FSDO is sure to dot all the 'i's. I'm open to suggestion. - Mike |

Now listen heah, Mr. Kearns, you anal retentive. Go to Home Depot and buy
one of those brass ball valves with teflon ball. Hell, buy several of them. Some of them are called "bolla valvola" giving you an idea where they are made.* Soak them in mogas or 100LL or both for a decade and see if one of the damn things fails. I get angry at Jim Weir every once in a while, but you know the guy has practical good sense that others are often devoid of. "Gene Kearns" wrote in message ...

The valves were made in Italy and the pistons in Brazil. Didn't bother me a damn bit. |

" jls" wrote in message ... Are you totally clueless? Have you never heard of proximate cause as a condition precedent to getting into court on a personal injury or wrongful death lawsuit? No, and apparently neither have the lawyers that have obtained multimillion judgements against companies like Parker-Hannafin even when the NTSB concluded their products were working just fine (Carnahan case), or when it was absolutely crystal clear that the crash was a result of the captain deciding to commit suicide (Silk Air flight MI-185). What was it that you were saying about clueless? How are things in La-La Land these days? sheeshh.... |

In fact, I think the word you are grasping for is "expedient." No thanks for your defective Thesaurus, not a synonym for "practical." *You* are the grasper here, and I doubt you have knowledge or experience in the upkeep of old airplanes like Michael's. That's the reason why he should consult with a *reasonable* A&P, not an anal one. I've known of A&P's who didn't know the difference between a Taylorcraft and a Chris Craft, and your strawman is duly noted. What one does is seek out a reasonable A&P, thank goodness for the abundance of competent A&P's in my neck of the woods. If you run up on an anal one, shun him and go to one with practical sense who knows how to interpret the FAR's reasonably enough and safely enough to keep the old airplanes flying. |

I plan on talking with the local FSDO
Then you will never be able to do it. Never. Once they know you had plans to do it, you lose plausible deniability. Look, here's the way it is. All alterations to the fuel system are major. You have no approved data. You have an unapproved part. It would take an STC or field approval to make it happen, and you won't get one. You're stuck with either your obsolete, leaky, marginally safe - but legal - valve, or you make the alteration yourself, by dark of night, and don't tell anyone. And make sure you have the kind of IA who doesn't notice such things. Michael |
