## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT RETURNED TO PHX. FLIGHT CREW REPORTED BLUE HYDRAULIC LOSS OF PRESSURE AFTER GENERATOR 1 KICKED OFFLINE THEN RECOVERED. THE AIRCRAFT LANDED SAFELY AT PHX AND TAXIED TO THE GATE UNDER ITS OWN POWER. **ORIGINAL REPORT WAS AALA202312180885** MAINTENANCE DETERMINED THE GENERATOR 1 FAULT CAUSED THE HYDRAULIC PRESSURE LOSS AND FOUND THE #1 ENGINE GENERATOR FEEDR CABLE CONNECTOR BURNT / DAMAGED. MAINTENANCE REPLACED THE #1 ENGINE IDG HARNESS FEEDER CABLE CONNECTOR BETWEEN 400VCI AND LUG 400VTI. THE IDG HARNESS ON THE #1 ENGINE WAS REPLACED (AALA202401053323) ALONG WITH THE#1 ENGINE IDG (AALA202401058682). A SATISFACTORY LEAK / OPERATIONAL CHECK WAS ACCOMPLISHED.
