## Discrepancy

(CAN) ENGINE FAILED POWER CHECK PLUS 4 TO BAD, PILOT DID 3 POWER CHECK ALL FAIL BY A FEW DEGREES C.  CHANGED THE FDC FILTER AS IT WAS DIRTY AND ALSO DID A COMPRESSOR WASH AND INSPECTED THE COMPRESSOR AND TURBINE BLADES, NO DAMAGE NOTED.  WE DID A GROUND RUN TO CHECK FOR AIR LEAKS AND DID ANOTHER 3 POWER CHECKS, ALL 3 POWER CHECKS FAILED BY THE SAME AMOUNT AS BEFORE.  WE THEN DID A CHECK OF TOT THERMOCOUPLE AND IT CHECK OUT OK.  DECIDED TO CHANGE THE VEMD WHICH HAS THE TOT INSTRUMENT IN IT, BORROWED ONE, ANOTHER 3 POWER CHECKS, THIS TIME IT PASSED ALL 3 TIMES BY -48 TO -50 C. THE VEMD WAS RECORDING ABOUT 51 DEGREES C, HIGH.
