| Subject: | Matco Brakes and Wheels |
Hi all,
I spent most of today changing the tyres on ELZ. "That's a bit slow" I hear you
say. Well yes, it is, but it turned out to be a much more educational experience
than bargained for.
First off, some time in the last one or two flights one of the through bolts on
the left hand wheel had broken and allowed the wheel to distort somewhat so that
it did not want to slide off the axle. Easily fixed, let the pressure out
of the tyre and all was well. The big question is why did the bolt break?
The fault may not be as simple as an inadequate bolt. The tubes supplied with
the kit have a washer and nut on the base of the valve stem. In my example, the
washer was chewed about a bit and there was some corresponding damage around
the valve stem opening in the two halves of the rim. I cannot tell if this
damage occurred before or after the bolt broke but it is possible that the washer
became caught in the opening when the wheel was assembled, wedging the halves
apart, and subsequently worked free and left he bolt loose to flex and fracture.
I would like to think that I would have picked this up during assembly
but the possibility exists.
I remember that others have had bolts break in these wheels so there is obviously
a design fault. I wonder why Matco has not fixed it and issued some advice
to operators, I also wonder why there has been no remedial advice from Arion.
I removed the nuts and washers from the valve stem and replaced all the cap screws
with high tensile items which should fix the problem.
The next learning experience goes back to to a Matco service bulletin issued last
year, see Lightning newsletter of July 2010 for detail. This deals with the
screws which attach the brake disc to the rim and identifies problems with a
screw and washer combination different from that supplied in my kit. There is
also advice from Arion that the problem identified by Matco does not apply to
wheels with the Allen head cap screws with lockwire safeties as in my Arion
kit, and, as far as I know, most others.
I'm here to tell you that it ain't necessarily so! When I removed the cap screws
securing the disc to the wheel there was evidence that the disc had been working
on the screws. There was no obvious free play but the evidence of movement
and fretting indicated that there was not enough tension on the fastening
because the screws were bottoming out in the holes in the rim. Subsequent inspection
confirmed this. The fault was not obvious in a daily inspection, even
without spats fitted and I know of one other occurrence of this problem so I
respectfully suggest that a careful check of your disc attach cap screws may be
in order.
I shortened my cap screws by a couple of millimetres and reinstalled and I believe
this will cure the problem.

Cheers, Selwyn

I had a feeling that Nick didn't want to finish our class but He had other things
on his mind for sure. Congratulations to you both. Enjoy him all you can
as they grow up so fast. Are you thinking about having a formation team in the
future? Harry

Hey everyone,
I just got a notification from Katie that Nick and Dana's baby has shown up a week
or so early. It's a BOY!!!! Cale James Otterback .
Obviously a future Lightning pilot and more than likely, a future IAC aerobatic
champion flying Nick's Pitts.
So congratulations to Dana and Nick, and welcome to our group, Cale.
Blue Skies,
