## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED AND THE AIRCRAFT RETURNED TO SMF DUE TO THE FLIGHT CREW REPORTING MULTIPLE BIRD STRIKES DURING CLIMB OUT ALONG WITH A #1 ENGINE STALL / SURGE AND THE ENGINE THEN CAME BACK. THE AIRCRAFT LANDED SAFELY AT SMF AND TAXIED TO THE GATE UNDER ITS OWN POWER. MAINTENANCE ACCOMPLISHED A BORESCOPE INSPECTION ON THE HPC AND FOUND DAMAGE THAT EXCEEDED LIMITS REQUIRING THE ENGINE TO BE CHANGED.  MAINTENANCE REPLACED THE #1 ENGINE AND ACCOMPLISHED A SATISFACTORY OPERATIONAL CHECK PER TASK CARD 26L40071004.
