## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARD INBOUND INTO LAX DUE TO THE FLIGHT CREW REPORTING THAT ON DESCENT AN ECAM FOR YELLOW HYDRAULIC RESERVOIR LOW LEVEL DISPLAYED. THE AIRCRAFT LANDED SAFELY AT LAX AND WAS TOWED TO THE GATE. MAINTENANCE REPLACED THE YELLOW HYDRAULIC RESERVOIR TRANSMITTER GAUGE PER AMM 29-13-41 WHICH CLEARED THE FAULT.
