## Discrepancy

AFTER DEPARTURE FROM WEST PALM THE PILOTS EXPERIENCED A VIBRATION AND A YAW IN THE AIRCRAFT. THE PILOTS DECIDED TO RETURN TO WEST PALM, AND AFTER LANDING WHEN THEY GOT OUT OF THE AIRCRAFT THEY NOTICED THE LT ENGINE COWL WAS COMPLETELY MISSING. THIS HAS HAPPENED SEVERAL TIMES ON OUR FLEET. THE CAUSE IS UNKNOWN, BUT COULD BE THE AIR GOT UNDER THE COWL AND STARTED TO PEEL IT BACK UNTIL THE COWL WAS COMPLETELY GONE.
