## Discrepancy

(CAN) THIS VALVE WOULD CLOSE FULLY, BUT WHEN SWITCHED TO THE ON, OPEN POSITION FOR FLIGHT OPERATIONS THE BALL VALVE WOULD ONLY OPEN 1/3 OF THE WAY.  THE HELICOPTER RAN FINE DURING START UP, IDLE, AND LOW POWER FLIGHT OPERATIONS, WHEN THE POWER WAS INCREASED TO BETWEEN 90 PERCENT TO 100 PERCENT TORQUE FOR A PROLONGED PERIOD. DURING A CLIMB OVER A MOUNTAIN THE FUEL FLOW TO THE ENGINE COULD NOT KEEP UP WITH THE DEMAND AND THE ENGINE FLAMED OUT.  THE PILOT ENTERED AUTO ROTATION AND PERFORMED A SAFE LANDING WITH NO INJURIES TO PEOPLE ON BOARD, AND THERE WAS NO ADDITIONAL DAMAGE TO THE HELICOPTER DURING THE EMERGENCY LANDING.
