Re: New Service Bulletin rev. B

I saw this text on the factory website:

"Taylorcraft Aviation mailed the AD notice to 2750 Taylorcraft owners. Due to the expected initial high volume of orders, Taylorcraft will manufacture and ship new lift struts on a first ordered, first shipped system.

The average time from order to shipping will be approximately twenty days. This is subject to material availability, only one company is manufacturing the 4130 streamline tubing at this time. "

I have no doubt Harry expected a high volume of orders.

The average time from order to shipping on the BD-5 kit was supposed to be something like 14 to 21 days. The average time Saddam Hussein expected to defeat the United States forces in Iraq was a week or two.

"Subject to material availability"... I suspect most of the streamline tubing from that manufacturer will be headed to Alaska and Colorado, and Taylorcraft may indeed have "availability" problems.

Re: New Service Bulletin rev. B

The news is out, easy there Bill , not the same material. Univair makes theirs from round tube, Airframes Inc. are the Piper section now approved for STC onto Taylorcraft. Don't compare apples and oranges.
Time will tell. kind of like the Indians & Sox , back tothe game!

Re: New Service Bulletin rev. B

I just downloaded, saved and printed the Rev B to the Service Bulletin from the factory web site www.taylorcraft.com please do so . The AD will be revised soon to reflect the new SB & time situation. good night!

Re: New Service Bulletin rev. B

Does this mean we have 90 days from now to comply??

Re: New Service Bulletin rev. B

I just read SB REV B.

What a bunch of crap.

So that's it, we have to disassemble our aircraft and ship the struts all over the country, costing hundreds of dollars and risking the chance of doing fatal damage to our wing fittings or damaging the wing itself, every 4 years.
That is still onerous and indicative of the fact that Taylorcraft is hoping we will give up and buy new struts from them. (at 30% or the original cost of my airplane)
The last interval was 60 years and no one fell out of the sky from broken struts. What happened to the intervals suggested by the EAA and AOPA?

What is with insisting that the struts be removed?

Failure criteria: If not just right here or just so there or even suspect, part must be failed.

Notice the tolerance table: The .035 tubing is allowed to be minus .004 which would make it .031 original, but you are only allowed .029 final which is .002 of corrosion. That is like a very fine layer of dust. What is the tolerance on the measuring equipment--maybe +/- .005? That is going to produce a lot of "suspect" measurements, even with perfect tubing.

What is with all the detailed technical instructions? Do this and that exactly and precisely this way, using exactly this kind of equipment and holding your mouth in such a position. Worse than a MIL-Specification.

Of course the AD will say "do it to the SB."

WHEN DID THE FAA START PUTTING THE FOX IN CHARGE OF THE HEN HOUSE?

I guess that doesn't leave much confusion in anyone's mind of how I feel about this latest rev.

Strut SB Rev B

In reference to the thickness table:

If .031 (.035 minus .004) is safe on one Taylorcraft for the entire strut, why

is .034 or .040, in smaller areas, not safe for others??

Back to physics class guys, or at least basic math.

Re: New Service Bulletin rev. B

One hopes that exclusion of the eddy current testing in this (new and improved) revised SB doesn't also exclude it as a valid inspection procedure for those of us who have already had it done!
