## Discrepancy

THE CREW REPORTED THAT AFTER TAKEOFF THAT THE LG WOULD NOT RETRACT & THEY HAD A LG AIR & GND FAIL MSG.  THE CREW ALSO REPORTED THAT THEY RECEIVED A SPOILER FAIL MSG, AN ENG 1 & 2 IDLE STOP FAIL MSG, GUST LOCK INOPERATIVE MESSAGE & THE THRUST REVERSER WAS NOT AVAILABLE.  THE AIRCRAFT RETURNED TO FIELD LANDING WITHOUT INCIDENT. MAINTENANCE REPLACED THE LG ELECTRONIC UNIT.  OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
