I had a couple of cracks in the engine mount that
could only be detected by a trained eye. There was just a little wrinkle
in the paint. There was never any shimmy or other symptoms. I
happened to be in Redmond at the time and took it over to Lancair and their
welder rewelded it and welded gussets in the "corners". It saved me
from moving the engine. I was told that there is no way it is going
to crack now. It is such a simple fix until I don't know why they are not
made with the gussets from the start. Maybe they are now, because he
already had the gussets made up.
The point is, to look at the paint on the welds very
closely. If there is the least wrinkle, investigate further.

Makes me wonder if it wasn't an engine mount problem instead of
the nose strut. That's quite a nose wheel shimmy. We're all happy for you that
it wasn't worse.
