Chuck,
    So relieved that the failure was benign enough to allow you to pick where
and how to land.........Like all of the "Rotorheads" I will be waiting to hear the
cause of compression loss........Along the same line I and others will be
interested in how the "TES" O-rings in your rotor side oil seals were holding
out.........You and Mark Steitle are the only ones currently using them in
your engines rotors (that I am aware of) and Mark has only ground run time
on his 20B.........How many hours do you have on them now ?
