## Discrepancy

DURING CRUISE FLIGHT, THE PILOT NOTED THAT THE GEAR HAD UNLOCKED FROM THE UP AND LOCKED POSITION AND OBSERVED A HYDRAULIC LOW PRESSURE CAS MESSAGE.  THE PILOT DIVERTED TO BIRMINGHAM INTERNATIONAL AIRPORT, KBHM, WHERE HE LANDED WITHOUT FURTHER INCIDENT, ALTHOUGH HE HAD TO BE TOWED OFF OF THE ACTIVE RUNWAY.  INVESTIGATION REVEALED THAT THE HYDRAULIC POWER PACK WAS FAILED.  THE POWER PACK WAS REPLACED BY EMBRAER TECHNICIANS AND APPROVED FOR RETURN TO SERVICE TO RETURN TO HOME BASE, KRDG.  THIS WAS THE 14TH POWER PACK INSTALLED IN THIS AIRCRAFT SINCE THE SPOILER INSTALLATION MODIFICATION PER EMBRAER S/B 500-00-0009 ON APRIL 2015.
