## Discrepancy

THE CREW REPORTED THAT THEY RECEIVED TWO MAINTENANCE CAUTIONS. ONE FOR L ELEVATOR G AUG AND ANOTHER FOR L ELEVATOR IAS AUG. THE CREW DECLARED AN EMERGENCY AND RETURNED TO FIELD. MAINTENANCE REPLACED THE LEFT-HAND POWER ELEVATOR CONTROL UNIT. OPERATIONAL CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
