Narrative:
Shortly after departure while climbing through 10000 ft, we heard a loud noise associated with a partial loss of thrust in the left engine. After reviewing engine indications, we noticed abnormally high egt. Although no vibrations or other abnormalities were noticed, I chose to return to msy airport. Following landing no reverse thrust was used on the effected engine. After arriving at our gate the engine was finally shut down. No emergency was declared and we landed below maximum landing weight.
