## Discrepancy

GEAR DOOR OPEN LIGHT STAYED ON AFTER GEAR EXTENSION.  GEAR SHOWED DOWN & LOCKED..  FOLLOWED QRH & GEAR DOOR LIGHT REMAINED ON.  THE FLIGHT DECLARED AN EMER.  DUE TO QRH PROCEDURES, THE MLG DOORS REMAINED OPEN DURING LANDING, CAUSING DAMAGE TO THE MAIN GEAR DOORS.  R & R LG CONTROL VLV IAW AMM 32-32-01.  ACCOMPLISHED LG CONTROL VLV OPERATIONAL & LEAK CHECKS IAW AMM 32-32-00, OK FOR SERVICE.  ALSO REPLACED BOTH MLG DOOR BUMPERS & HARDWARE IAW AMM 20-30-00.  THE ACFT WAS GNDED.
