What was found
(CAN) AFTER ROTATING AND CLIMBING TO 500FT, PILOTS HEARD A LOUD BANG AND COULD SMELL A BURNING ODOR. ALL GAUGES AND LIGHTS WERE FINE. PILOTS ELECTED TO RETURN TO THE AIRPORT AND LAND IMMEDIATELY. DURING THE TAXI OUT OF THE RUNWAY, PILOTS OBSERVED A LT ENGINE VIBRATION LIGHT AND COULD SMELL THE BURNED ODOR AGAIN. THEY IMMEDIATELY SECURED THE LT ENGINE. A MAINTENANCE REPAIR TEAM (MRT) WILL BE DEPLOYED.
