## Discrepancy

DURING TAXI, THE ENGINE SHOWED HIGH VIBRATIONS. PILOT SHUTDOWN THE ENGINE. INSPECTION FOUND ENGINE PROPELLER WITH A LOOSE BOLT, CAUSING THE BLADE ANGLE TO CHANGE, WHICH CREATED IMBALANCE.  ENGINEERING RECOMMENDED TO REMOVE POWER SECTION FOR INSPECTION & REPAIR, AS THE ENGINE SUFFERED VIBRATION.
