Analysis
A helicopter involved in a logging operation was in process of lifting a log when crew reported a 'loud explosion' and a loss of power was experienced. An autorotative landing was accomplished and a small engine fire was extinguished. The 1st stage turbine disc had separated and was uncontained. Debris had damaged the main rotor blades and cowling during its departure from the helicopter. Evidence of a thread lure was reported on the male and female threads for the disc bolts. This is the second reported igt turbine disc failure on this engine, both were being operated by this company at the time.
