## Analysis

AS NEAR AS CAN BE DETERMINED, THIS WAS THE PLT'S SECOND FLT SINCE OBTAINING HIS MULTI ENGINE RATING AND THIRD FLT SINCE OBTAINING HIS COM'L PLT CERTIFICATE FROM A DESIGNATED P.E. THE ACFT WAS OBSERVED TO DEPART LAWRENCE CO. ARPT AND UPON REACHING A POINT OVER THE RWY END, AN ENGINE STARTED MAKING A POPPING SOUND. THE PLT RADIOED ON UNICOM THAT HE WAS HAVING TROUBLE WITH THE ACFT. THE ACFT CLIMBED TO AN ESTIMATED 500 FT AND A LEFT TURN AWAY FROM THE OHIO RIVER AND TOWARD THE HILLS WAS STARTED. WITNESSES OBSERVED ACFT PORPOISE IN FLT AND SAID THAT AT LEAST ONCE IT SOUNDED AS IF BOTH ENGINES QUIT MOMENTARILY THEN RESTARTED. THEN ACFT ROLLED INTO LEFT BANK AND STRUCK TREES ON RIDGETOP.
