## Discrepancy

AIRCRAFT RETURNED TO PLATFORM AS A CONSEQUENCE OF LEFT ELEVATOR POWER ON LIGHT DID NOT TURNED ON DURING FLIGHT CONTROL TESTS.  ELEVATOR WAS CHECKED PER FREE MOVEMENT, ACCUMULATOR PRESSURE AND HYDRAULIC QUANTITY WERE CORRECT.  LIGHT REPORT WAS DEFERRED IAW MEL 27-14.  DURING OVERNIGHT SERVICE ELEVATOR PRESSURE SWITCH WAS REPLACED IAW MM 27-30-12, TESTED CORRECT.
