## Discrepancy

ABORTED TAKEOFF DUE TO NR 1 ENGINE N2 OVERSPEED AND EGT AMBER.  DUE TO 2.5 BLEED ACTUATOR MALFUNCTION THE BLEED VALVE FAILED IN OPEN POSITON RESULTING IN HIGH EGT. DEN MAINTENANCE REPLACED THE 2.5 BLEED ACTUATOR AND LUBRICATED THE 2.5 BLEED VALVE ACTUATING MECHANISM.  N2 WAS 100.1 FOR 1 SEC AND THAT WAS WITHIN JRH ACCEPTABLE LIMITS.
