## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED INBOUND INTO DFW DUE TO THE FLIGHT CREW REPORTING THAT THE LANDING GEAR WOULD NOT COME DOWN WITH MULTIPLE RECYCLE ATTEMPTS. AFTER A GO AROUND AND ANOTHER ATTEMPT, IT FINALLY CAME DOWN. THE AIRCRAFT LANDED SAFELY AT DFW WITHOUT FURTHER INCIDENT. **ORIGINAL REPORT WAS AALA202508042454**  MAINTENANCE REPLACED THE LANDING GEAR LEVER CONTROL PER AMM 32-31-11 AND REPLACED THE LANDING GEAR GREEN HYDRAULIC SYSTEM PRIORITY VALVE PER AMM 29-11-33. (AALA202508069621) A SATISFACTORY LEAK / OPERATIONAL CHECK WAS ACCOMPLISHED WITH NO ISSUES NOTED.
