## Discrepancy

PILOT REPORTED DURING CLIMB/CRUISE FLIGHT THE RIGHT HYDRAULIC FLOW LIGHT CAME ON AND RIGHT ENGINE LOST POWER. UPON INITIAL INSPECTION, THE ENGINE WAS FOUND TO BE SEIZED.  PISTONS AT CYLINDERS 1-4 WERE FOUND TO BE IN THE TOP DEAD CENTER POSITION.  CYLINDER #3 WAS REMOVED AND WE CONFIRMED THE CRANKSHAFT IS FRACTURED AT JOURNAL BETWEEN 1 AND 3. ENGINE WILL BE REPLACED.
