## Analysis

ACCORDING TO THE PLT, THE ENG WAS NOT PRODUCING SUFFICIENT POWER TO MAINTAIN ALT IN NORMAL CRUISE. ALSO, HE REPORTED THAT 'EXTRA POWER' WAS REQUIRED ON FINAL APCH FOR LANDING AT THE DESTINATION ARPT. HE FURTHER STATED THAT HE WAS UNABLE 'TO CUT POWER TO IDLE' DURING THE LANDING. AFTER TOUCHDOWN, THE ACFT BOUNCED SEVERAL TIMES, PROMPTING THE PLT TO INITIATE A GO-AROUND. SUBSEQUENTLY, THE ACFT FLEW INTO A GROUP OF TREES APRX 1100 FT FROM THE DEPARTURE END OF THE RWY. AN EXAM & TEST RUN OF THE ENG WERE MADE, BUT NO REASON WAS FOUND FOR THE REPORTED ENG PROBLEM.
