  1. Those Weldon pumps only last about 300 hours in operation before the brushes wear out. They were reportedly working on a brushless motor but by the time of my retirement they hadn’t come out. (three years ago) I suspect they may never go brushless, but if they did that would pretty much eliminate motor wear as the life limit and make it pump wear, which seems to be minimal. So how many years does it take to accumulate 300 hours at maybe 10 min per flight? The pumps used on an S2R-H80 appear to be almost identical. http://www.kathrynsreport.com/2019/09/loss-of-engine-power-total-thrush-s2r.html Oh, and the pump in that accident was a red herring, it had nothing to do with the accident.
  2. jlunseth, A very good dissertation, I assume you have a Law background? I was. trying to point out, I guess rather poorly that I’ve seen compliance with an AC in an enforcement action used against a person based on they are advisory only and not a reg. It is a catch 22, and one that I’m certain that is intentional. I’ve been pushed into compliance with an AC during a aircraft certification even when it disagrees with the reg. Then there are the catch all’s too of course, like operating in an unsafe manner, you weren’t in violation of anything but they can still “get” you. My favorite is your certifying a CAR 3 airplane, but the FAA has a reg that states that they can make you comply with FAR 23 if doing so will materially improve safety, that’s a judgement call by the way, one that will very from day to day. Then you understand why the big boys have ODA’s The FAA was at onetime trying to make manufacturers come up with MEL’s, which is pretty easy to justify, for instance 91.205 doesn’t say fuel boost pump, so can we fly without one? Those of us that are fuel injected. Of course not because the checklist requires it to be on for certain phases of flight, but the FAA wants it to be a little more obvious than that I guess. The regs get more interesting with older aircraft, for instance my 1946 Cessna 140 doesn’t have a POH, so how do you comply with the requirement of carrying a POH in the aircraft?
  3. It may be that AS in Europe has it, but the US Spruce doesn’t?
  4. When talking about electrical fires you really open up a can of worms. PVC/Nylon wire which was discontinued I believe in 1972 is about he only wire used in our category of aircraft that will actually burn, however nylon wire ties will burn rather well and in my opinion should never be used, they also will break wires, wires should be laced not tied. Brings us to clamps used for bundles of wires, the ones with black rubber, I believe the rubber will burn, the ones with thinner white covering won’t I don’t think. CAR 3 burn standards are rather “loose” so in truth if your concerned about furnishings burning, you need to replace all of the furnishing in the aircraft with something that meets FAR 23 standards Hopefully we don’t have any Kapton wire, I’ve looked and didn’t see any in my airplane, but of course couldn’t look everywhere. Kapton is easy to spot, it’s a reddish / amber color, not white, if there you can’t miss it. If fires concern you, and they should, get a good Halon fire extinguisher, don’t cheap out with a dry chemical one, discharge a dry chemical one in a cockpit and you won’t be able to see or breathe. If your an environmentalist and are against Halon, there is Halotron, not as good as Halon, but better than nothing. I don’t know if it’s approved, maybe only Halon is. Many countries have outlawed Halon, I don’t know what they do. I was going to start a thread on where to mount a fire extinguisher on a Mooney, considering it needs to be mounted in a place that the pilot can get to it while flying, other aircraft I’ve mounted one either between or in front of the pilots seat, neither seems to be viable in a Mooney, so I don’t really know where to mount one. As a kid I was trapped under a farm tractor and burnt down my shoulder and back from hydraulic fluid, plus I was sure that it was going to burn as the battery shorted against the hood of the tractor and burned through the steel and fuel was draining out over everything so I’m afraid of fires more than the average person. But I’m not worried about the windlace, especially when the one the airplane came with is fabric covered cardboard, sure the cardboard could have been treated who knows?
  5. I know burn certs aren’t hard to find or all that expensive to have certified, However people are often told by many that you must have burn certs and for that reason you must buy our aircraft interior, even though the local guy who does classic cars can do much better for less, you can’t use his interior, it’s not certified. So they end up an overpriced cheap interior. ‘A CAR 3 airplane only has to have burn certs for those compartments where smoking is allowed, if smoking isn’t allowed, no burn certs are required. ‘You also must supply ash trays in the compt if smoking is allowed too, so if you have removed ash trays, you should placard the aircraft No Smoking. If memory serves these had to be a particular type of ashtray too, I think they had to have a lid so a cigarette would smother, but not certain. Where I worked we built new aircraft that had no ash trays and the interior materials had not been burn certified because we placarded the aircraft No Smoking.
  6. I still have a Sailrite sewing machine and I think the foot you speak of, but I just bought some already made, I’m not checked out on the sewing machine ‘I expected someone to bring up burn certs, as this is a CAR3 airplane I’ll just placard it No Smoking, I wouldn’t allow that anyway.
  7. Just looking at it, it appears to be a small job, except it seems the interior plastic needs to be removed, then I believe it’s simply screwed into the door mold with small PK screws. ‘I’ll know in a week or two anyway
  8. Ordered 4 yds of cloth windlace for $28. Seems to be a simple job, original was cloth covered cardboard, maybe 3/8”? What I ordered is cloth covered foam, 1/2” . Half inch seems to be the common size. Maybe 41 years ago the cardboard was 1/2” who knows? I have an inflatable door seal, it seems to work excellent, and I don’t inflate it and as far as I can tell, no wind noise.
  9. What is the purpose of this? Is there a replacement available? Has anyone simply removed it, I can’t see a purpose except maybe to cover the opening appearance wise? Mine looks bad is broken and torn etc, I’d like to replace it if possible or just remove it if there are no replacements available.
  10. If I had to buy one, I would buy LED, and of course delete the strobe power supply and save that weight and money
  11. He is a Havamalt, it’s a “designer” breed, half Maltese, half Havanese. We were living on a sailboat when we bought him a year or so ago and he doesn’t shed, which is a desirable trait in small quarters. His name is Mikey How are you rotating the photo’s?
  12. It’s not in their current catalog, so I called and they couldn’t find it either, so it may no longer exist, at least not at Spruce
  13. Here is the catch with an AC, the A stands for what? That’s right they aren’t regulatory, I know the FAA has a tendency to try to act as if they were, so why don’t they make them FAR’s?
  14. Ref the STC thing, I believe it’s some sort of marketing game to try to convince people that the outrageous price they are paying for an item is justified, you know an X has to have an STC, so that’s why a piece of plastic is so expensive. For instance there are electric clocks that have STC’s, so to remove one brand of electric clock and replace it with another is an STC? That’s a Major, really?
  15. AOL.com, seriously? I thought that went away long ago.
  16. Not saying it is, but when you turn the nose wheel. the pedals are of course moving too. never mind as I kept reading I see you found and fixed it
  17. Went out this afternoon, she woud run fine at 20” and 2200 up to 6 GPH, any less and it would pickup a little roughness. 7,500 ft 6 GPH is still awfully good though Object of today’s flight was to see how our little dog took to flying, he did OK,a little apprehensive, but he will do fine given a little time. How do you rotate a image because the forum software rotated it.
  18. Best answer I have is that it’s an STC, Rosen convinced the FAA that is was a major alteration, so it takes an IA to sign the 337, so if your IA will sign it, your good. Or said another way, you need to ask him or her.
  19. Before you guys go buying devices to advance timing etc., might want to give Hartzell a call and ask what they can do to propellers. ‘Ask their opinion
  20. I don’t plan on any kind of refurb in the near future, interior isn’t all that bad, except for the roll trim around the door, which I’m thinking to just remove it, what function does it serve anyway? Anyway I called Spruce the ashlight isn’t in their catalog and the guy never heard of it either, so I guess no longer?
  21. I’m thinking maybe more like this one, but I’m hoping someone will know, they have to be from some kind of older car,GM’s are common so maybe? https://www.summitracing.com/ga/parts/oer-k813?retaillocation=ga
  22. I’m not arguing with you, but in fact HP, fuel economy and emissions have never, ever been better. Today’s cars are the most powerful ever produced, pollute the least, and are capable of phenomenal mileage. ‘My Wife’s car is the fastest four door coupe that’s ever been mass produced, a CTS-V Cadillac. We get almost 25 MPH on the road, spark plugs last 100,000 miles so no tune ups for 100,000 miles, and it passes emissions, idles smooth etc. Our other car that the Daughter has in College is a 2010 Toyota Prius that’s closing in on 300,000 miles, and when I drive it, it gets close to 60 MPG, my best was 72.3 MPG hypermiling it. Autos that will easily last over 250,000 miles carrying four passengers and luggage while getting in excess of 60 MPG and exceedingly low emissions is easy, was done over a decade ago. But it’s not what people want, if you built it, it wouldn’t sell. People want huge impressive four wheel drive SUV’s that may on a good day get 20 MPG. Even the last generation of the Prius when Toyota was faced with making it way more efficient chose instead to make it bigger, heavier and with a larger more powerful engine and leaving fuel economy the same. Now People want big impressive four wheel drive electric SUV’s that will use at least three times the energy of an efficient sedan would.
  23. I have been down this route with different regulatory agencies including the FAA. If it’s installed in the aircraft, and there is no required equipment list, then from a regulatory perspective, it has to work. The line of thought is how can a pilot determine what equipment is necessary for flight if it’s not called out in a min equipment list? Trust me pointing out the required equipment list in part 91 won’t work. My answer would be to not make a write up in the logbook or placard the piece of equipment as inop, and if asked, which is extremely unlikely, I mean less likely than winning the lottery. answer that it broke on the last flight.
  24. My ashtrays are rusty and look like crap. so I’d like to replace them with something, 81 J model as I assume they may be different by year ‘Searching finds a device called an ashlight that some say Spruce has, but I can’t find it on a search. New ash trays would be preferable if they exist, Univair lists two Cessna ash trays, one is $125 ea, the other like $600 ea. so that’s out even if they are correct. These things have to come from somewhere else, some kind of car or boat maybe? can’t be aircraft specific ‘Anyone have a source on replacement ashtrays or ash lights or anything to plug those holes?
  25. Going off of memory a NAS bolt is not a close tolerance bolt. ‘However the difference between an AN and NAS is that the NAS is significantly stronger OK, looked it up an AN bolt is 125,000 tensile strength an NAS is 160,000 both can be close tolerance, if they are they have a triangle on the head.
