## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT RETURNED TO PHX DUE TO THE FLIGHT CREW REPORTING THAT ENGINE 2 EGT OVER LIMIT ON TAKEOFF. THE FLIGHT CREW SHUT DOWN THE ENGINE AND LANDED SAFELY AT PHX WHERE IT TAXIED TO THE GATE UNDER ITS OWN POWER.    A REVIEW OF THE DFDR DATA RESULTED IN THE DETERMINATION THAT THERE WAS AN EGT INDICATION ISSUE. MAINTENANCE REPLACED ALL OF THE EGT THERMOCOUPLES AND LEADS PER AMM 77-21-10.
