What was found
AFTER TAKEOFF ON THE MIA - MVD ROUTE, A MESSAGE FROM THE LEFT ENGINE CONTROL WAS PRESENTED TO THE CREW. IN COMMUNICATION WITH THE MOC, THE CONVENIENCE OF RETURNING TO MIA WAS DETERMINED BECAUSE MVD DID NOT HAVE THE NECESSARY RESOURCES TO CORRECT THE FAIL. UPON RETURN OF THE AIRCRAFT TO THE MIA STATION, IT WAS IDENTIFIED THAT THE EEC WAS NOT IN THE CONFIGURATION FOR THE DISPATCH. THE PCMCIA IS READ AND IT CONFIRMS THE FAILURE OF THE EEC; THE LT ENGINE EEC IS REPLACED AND PERFORMS AN OPERATIONAL TEST WITH SATISFACTORY RESULTS.
