## Discrepancy

AIRCRAFT WAS NOT GROUNDED: THROUGHOUT CLIMB, ENGINE #2 WOULD NOT PRODUCE SPECIFIED CLIMB THRUST, WITH N1 CONSISTENTLY 1.5% LOWER THAN ENGINE #1 AND A CORRESPONDING LOWER FUEL FLOW. SIGNIFICANT BECAUSE ENGINE #2 BLEED WAS CLOSED IAW MEL 36-01B. IF ANYTHING, THE CLOSED BLEED VALVE SHOULD HAVE MADE IT EASIER FOR ENGINE #2 TO ATTAIN CLIMB THRUST. MAINTENANCE REPLACED THERMOSTAT SOLENOID 10HA1 AND ACCOMPLISHED A SATISFACTORY LEAK / OPERATIONAL CHECK PER AMM 36-11-55.
