## Discrepancy

PILOT REPORTED LEFT GENERATOR FAILED IN-FLIGHT.  AFTER RE-SETTING LEFT GENERATOR.  BOTH GENERATORS WENT OFF-LINE.  IT WAS ALSO REPORTED THAT RIGHT OR LEFT GENERATOR WORKED ALONE, BUT REGARDLESS OF WHICH ONE WAS ON-LINE, BRINGING THE SECOND GENERATOR ON-LINE CAUSED BOTH FAIL LIGHTS TO ILLUMINATE.  LEFT GENERATOR WS REPLACED WITH SERVICEABLE UNIT AND THIS SOLVED THE PROBLEM.
