## Probable cause

the fracture of one 1st stage turbine blade from a high cycle fatigue crack that originated from a break in the coating on the leading edge of the blade.

Contributing to the uncontained release of turbine material was the yielding and rupture of the turbine exhaust case wall after turbine debris collected at probes in the case.
