## Discrepancy

FLIGHT 1888, PHL - BOS - AFTER TAKEOFF THE LANDING GEAR WOULD NOT RETRACT.  LEVER WOULD NOT MOVE OUT OF THE DOWN POSITION.  AT ROLL OUT THERE WERE THREE EICAS MESSAGES; ENGINE 1 AND 2 NO DISPATCH, AND FLIGHT CONTROL NO DISPATCH.  ALL FUNCTIONS OF WEIGHT ON WHEELS SWITCH WORKED NORMALLY.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE LEFT MAIN LANDING GEAR "A" SYSTEM SENSOR PER TASK 32-62-03.
