Hi Steve,

No definite proof, but I am quite sure that it was due to excessive exhaust
gas temps eventually melting away part of the inconel turbine blade and
making the turbine unbalanced. I mostly flew around at peak EGT but now I
will be more careful about keeping the EGT less than 1600.  The last turbo
lasted 170 flight hours... will try to do better next time.
