## Analysis

THE ACFT ROLLED RIGHT AFTER A PREMATURE LIFTOFF DUE TO A DIP IN THE RWY. THE ACFT CONTINUED TO ROLL RIGHT UNTIL IT IMPACTED A 6 DEGREE SLOPE IN A 100 DEGREE NOSE DOWN ATTITUDE. INVESTIGATION REVEALED THAT THE RIGHT ENGINE HAD SUFFERED A POWER LOSS DUE TO A BLOCKAGE OF AN INTERNAL MUFFLER DIFFUSER. THIS ENGINE HAD A HISTORY OF MALFUNCTIONS, HARD STARTING, LOSS OF POWER ON TAKEOFF, ACFT YAWING IN FLT TO THE RIGHT & RUNNING TOO LEAN WITH HIGH CYLINDER HEAD TEMPERATURES.
