## Discrepancy

AIRCRAFT WAS NOT GROUNDED: INFLIGHT AFTER 1 HOUR 45 MINUTES FLIGHT DECK DOOR WOULD NOT OPEN. IT APPEARS THE TOP AND MIDDLE LOCK ARE THE ISSUE. WE USED THE UNLOCK SWITCH ON THE CENTER PEDESTAL FLIGHT DECK DOOR SWITCH. MAINTENANCE ADJUSTED FLIGHT DECK DOOR UPPER LATCH MECHANISM AND ACCOMPLISHED A SATISFACTORY OPERATIONAL CHECK PER AMM 52-51-21.
