Oh wow. Ok. I can certainly picture that. You might consider one of the aerospace welding shops that does engine mounts and such. They often have DERs on staff and can determine heat treat required. I think I’ve heard recently that ACS does nose trusses now, so this is not that far off. Another company used to be Kasolo (sp?). Don’t know if they are around. As others suggested, my guess is surplus will be fastest. Then you can get these repaired in a leisurely manner.

Do you happen to have pictures of the damage you are trying to repair?

Generally speaking, alternator regulators have some form of “crowbar” over voltage protection. When they detect over voltage, they intentionally cause the circuit breaker to trip. You might tap in a recording volt meter to see if your voltage spikes. This can also occur if the regulator is failing, as shown above.

Does he do good on a leash when out of the plane or do you carry him?

It is super frustrating that I can’t seem to find any clear combination of cross reference guides that would lead one to the right tube. When I bought the 70deg tubes, I was not 100% sure it would work, but could not find anything restricting them or, for that matter, anything that said you must use a straight stem. I would be curious if your mechanic has found a specific reference that requires a straight stem….I really have looked and can’t find that…. Knock on wood, I am still happy with the 70 deg, much easier to service than the straight stem or 90 stem on the 6” wheels. I use 90 on the nose wheel. I wish I could tell you which stem the 65 uses….I looked again and it reminded me of the difficulty I’ve previously had. If you have to bend a straight stem to service it, you may be a candidate for the 70.

Since you have an old federated system….individual intercom….and the intercom also failed….I would lean toward the ground….. The downside is that this is likely at the back of the radio rack and hard to access. You might start t shooting by having one person with headset on and another “jiggling” things under the panel. These can be frustratingly difficult. In some cases I’ve re-wired to ease the pain.

What equipment do you have, radios, audio panel, intercom? If you lost intercom too, I would be looking at a common failure like the audio panel racking or common ground point that is often used with audio systems.

@Kevin Westbrookfrequents the site. Here is a shout out. I’ve had my 430 driving the system for years. Works great. Start scanning eBay and MS for parts.

Consider contacting the manufacturer and see if you can get warranty. I want to say Spruce managed it for me last time. It is really frustrating that this continues to happen…

Are you looking for repair work? One of Britain’s techs, Kevin Westbrook, still does a bunch of repair work for folks. One can also still get paperwork from them as recently as a few months ago. Let us know what you are trying to do and we will help find an answer or point you to the right person.

Just to rant a little more. I’m not convinced that basic under inflation causes it. On tail wheel aircraft many of us run intentionally “under inflated”. I don’t believe they fail at a higher or lower rate. They certainly do not tolerate a pinch well, but I still believe that manufacturing is a bigger root cause. I’ve also been suspicious about the initial packing. They come folded from the manufacturer and I would contend the folded corners create a weak spot not unlike the pinch they tell us to avoid. Not sure how to prove or resolve this unless they store and ship them with light inflation. Anyway, take a close look when you get it off in case it is a simple pinhole defect. In each of my events I took off inflated and landed with a flat and it was an incredibly small hole and not hint of leaking prior.

There are a few threads on this topic. Could be a pinch, under inflation or another crappy tube. Take a close look. I’ve had three of them with pin hole leaks that were not caused by a pinch. The tubes simply seemed defective and seemed to lack adequate wetting of rubber when manufactured. Last one was less than a year old. If it can be shown to be defective, get in touch with the manufacturer. Mine was replaced. Also, do a service difficulty report. For as much as we pay for these things now, you would think they can get it right.

I didn’t understand the point of the question until later…I now understand the emphasis is on “active” vs “clear”. I think I usually say clear of XY. I might say “active” if there are planes in the pattern and it is clear what the active is, but to your point, why not say the number? I will certainly consider that in the future.

Didn’t know it was unapproved, but I find “clear of the active” useful at airports where there is a hump obscuring the opposite end of the runway.
