## Discrepancy

DURING RE-FUELING PILOT REPORTED A STRANGE ENGINE NOISE. AFTER SHUTDOWN MECHANICS FOUND A SECOND STAGE N1 BLADE HAD BROKEN AND EXITED THROUGH THE FREE TURBINE. THIS IS A PRELIMINARY REPORT FOR MEETING REPORTING DEADLINE. ENGINE HAS NOT ARRIVED AT THIS REPAIR STATION. PHOTO WILL BE SUBMITTED.
