About a month ago I got a new 4371 to install on a customers plane.
When I installed the nut, it locked up the whole impulse coupling
mechanism. I took some measurements on the new one and compared it to
the old one. It had been manufactured wrong. When I tried to return
it (to Aircraft Spruce), I was given a run-around for 3 days. They
wanted me to talk to someone in the technical department at Unison to
see if I'd installed it in the plane wrong. They (Aircraft Spruce )
couldn't believe I found a manufacturing defect BEFORE it was
installed. I made 30 phone calls to Unison over two days and never got
a reply back. Aircraft Spruce finally just sent me a new mag (I'd
already returned the first new mag).

I got the second new mag yesterday. It's also F'd U. I called Unison
5 times yesterday without anyone answering my call. I finally got
Aircraft Spruce to go through their supplier. Gee, they found out that
pretty much all of the mags made since GE took over have been
manufactured wrong. In the mean time, the next batch of mags is due in
June.

I took a bunch of pics showing the defect just in case someone wanted
to see it. Sending them now to Aircraft Spruce.
