Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The acft lost eng power & crashed while attempting an autorotation. Eng teardown revealed that the #2 bearing failed as a result of some of the ball retainers being broken & cracked between the ball pockets. This condition allowed the impeller assembly to move forward contacting the diffuser assembly resulting in a loss of eng operating power.
