## Discrepancy

CREW NOTICED A LANDING GEAR DOOR UNSAFE INDICATION IN FLIGHT.  THE GEAR WAS LOWERED WITH GEAR DOWN AND LOCKED INDICATIONS NORMAL.  INSPECTION REVEALED THAT THE OB RT GEAR DOOR HINGE WAS CRACKED WHICH CAUSED THE DOOR TO NOT FULLY CLOSE.  THE CONDITION WAS AGRIVATED BY HIGHT AIRSPEED. (K)
