## Discrepancy

WHILE HOVERING FOR TAKEOFF, IN A RT PEDAL TURN TO ALIGN THE AIRCRAFT WITH THE FLY AWAY WHEN A NOTICEABLE BANG CAME FROM THE ENGINE COMPARTMENT AND RT YAW OCCURRED.  IMMEDIATELY LANDED, CHECK ALL SYSTEMS IN THE GREEN AND HOVERED TO THE MAINTENANCE PAD.  MAINTENANCE INSPECTED COMPRESSOR INLET AREA FOUND NO EVIDENCE OF FOD, INSPECTED COMPRESSOR SECTIONS FOR CRACKS AND LEAKS NONE FOUND AND AIRLINES CHECKED GOOD.  REMOVED AND REPLACED BLEED VALVE, OPS CHECK WAS GOOD.
