Thanks

They have one less in stock now.  And yes, OUCH.

Ordered the V band clamp from Air Power a month ago and got notice last night that it had shipped.  Price was $830 shipped.

Mine too, maybe we got in before the increase?

And then there are these:

So what, there is no shortage of unapproved parts that could be installed. And probably no one will be wiser till there is an investigation after the accident. Can you imagine the law suits even if it wasn’t a factor in the accident? Regardless, why take chances with such a vital part.

I can't image that there are that many companies making these clamps.  And that there are any companies that is making the same clamp in an auto and airplane version with any difference.

That Garrett clamp looks suspiciously like the unlabeled spot-welded clamp with no part numbers on it that I recently replaced with a proper new riveted clamp after a 4-month wait. No mention in the logs of what the old clamp was or when it was installed. Before my ownership.

[Pritch]

Received my clamp today and after inspection there are no spotwelds only riveted.  There is also no way that one could add rivets to their old ones as the outer rivets are put in first and then the v band part is attached.

After seeing this thread I called TCM customer support 2 days  to inquire if the P/N 670105 supercedes the 653332 clamp shown on their online IPC. He said the correct part is what is shown on the website, (653332). He said he gets about 10 calls per week regarding availability. He also said they are working on it and are striving to have availability by the AD date.

I called the AD POC and he is very familiar with the problem. His solution was to call around and try to find a PMA part....

I have recently seen this scenario play out for multiple turbo'd engines on my field.  C182, Mooney K and TLS.   Turbo overhauls are now $6500 and up.    Another $5000 for TLS exhaust stacks.    PLUS the V-band clamps.

I would never purchase a turbo'd airplane.

Well now, hold on.  Which engine do you have exactly?  The TCM parts manual for my TSIO-360SB shows the original (spot welded) part as 653337 and it also states that the part is superseded by part 670105 (riveted).  This aligns exactly with the AD. These parts (670105) are shipping from various suppliers.  I got one last week.

Do you have a different engine variant that uses a different part number?

Heres a shot from the tcm online parts catalog:

A turbo charged airplane is a matter of preference. Personally, I don’t want a plane without a turbocharger. The cost of a turbocharger is minor compared to the overall cost of ownership. Being able to fly over the bad weather is worth it to me.

And haul ass in the teens instead of wheezing along to the point it’s just not worth going above 12.5 in an N/A most of the time but yea we pay for that premium.

Wow that ad sure way underestimated the price per clamp geesh!

But if you ordered it right after this was published it wasn’t very far off.

In reply to Ragsf15e, the engine is a TSIO-360LB1,  P/N 653332, in an M20K.  Screenshot from TCM today.  

It appears they recently updated their online IPC.  Their application listings for the 670105 shows the LTSIO-360 and the 550. Could be they haven't amended the 360-LB1 IPC yet.

I'm calling TCM customer support tomorrow, might get a different guy with different info.

After I got my 653337 clamp replaced with a 670105, my A&P called to ask if I'd seen anything to say it also can replace a 653332. He was working on a Seneca (which uses another variant of the TSIO-360) and I guess the IPC calls for a 653332. 

I didn't know the answer then, and still don't now, but he was having trouble finding guidance. 

I hope you get it figured out. What a mess.

Right about the time it went into effect, my FBO was able to order one from their normal parts supplier at around that price.
