## Discrepancy

RTFL DUE TO RESTRICTED ENGINE THRUST.   [07-31-07]  ON CLIMBOUT ENGINES PRODUCED ENOUGH THRUST FOR AN APPROX 1000' PER-MIN CLIMB RATE. TRUE AIR TEMP SHOWING +48C ON UPPER EICAS. SHOULD BE ABOUT 12 DEG-C.  TAT PROBE HAD A BIRD STRIKE DURING TAKEOFF AND THE NORMALLY ASPERATED PROBE WAS CLOGGED WITH BIRD REMAINS CAUSING INACCURATE TAT READINGS.  REPLACED TAT PROBE.
