This is the final word on the MT prop inspection and overhaul.  After
being advised that the blades were unserviceable, an inspection of the
blades at MT USA, proved that to be in error.  The blades are in-fact
serviceable and will be recovered and returned after completion of the
overhaul.  There is one item MT drivers should be aware of; when the six
year inspection is due you will have to have your hub machined to
accommodate the new stainless steel seal races at a cost of about
$1,000.  The prop is then overhauled because of the machining
requirement so plan on spending about $4,000 for the complete job.  I
don't know at what point MT began the new hub configuration, but if your
prop is 6-7 years out it is a good probability you will need the update.

"Dear Pat,

our people at MTP USA inspected the blades and they are fully airworthy
and have no cracks at all. The only marking we found was a shrinkage marking
in a bonding are. nothing else. So we will install the new blade ferrules
and put new glass fiber in the inner area of the blades then your blades are

like new again. We had to remove the glass fiber for inspection.

As I informed you we never had cracks and therefore I really wondered
what was going on. We trained our business people that they ask more detailed

and only let engineering answer a question in case somebody is asking
about cracks in a blade.

So it was and is safe to fly an MT-Prop."

I am thankful for the full inspection and appreciate the quick response
by MT.  I had visions of MT props coming apart, but now feel comfortable
with the fact that MT has never lost a blade.
