## Discrepancy

DURING ENGINE ADVANCING FROM IDLE TO FLIGHT, ENG #2 OIL TEMP INDICATION WENT BLANK. A TEST FLIGHT EVAL REVEALED  #2 ENGINE OIL TEMPERATURE DISPLAY ON VEMD FAILED WITHIN FIVE MINUTES OF START OF #2 ENGINE. THE DIGITAL SEGMENT UNDER THE TEMPERATURE DISPLAY WAS ALSO BLANK. DISPLAY INDICATED CORRECTLY ON PREFLIGHT AND UP TO THAT POINT. REPLACED TEMPERATURE PROBE. TEST PILOT MOC COMPLETED IAW FLM. ALL INDICATIONS NORMAL.
