THE PILOT REPORTED THAT DURING TAKEOFF, THE ENGINE DID NOT MAINTAIN FULL POWER. WHILE LANDING IN A RESIDENTIAL AREA, THE AIRCRAFT STRUCK A TELEPHONE WIRE AND THREE TREES. AN EXAMINATION OF THE ENGINE REVEALED NO OBVIOUS DEFECTS THAT WOULD CAUSE A LOSS OF POWER. THE THROTTLE QUADRANT, PN 40380, HAD SEVERAL DISCREPANCIES. THERE WAS NO EVIDENCE OF LUBRICATION OF THE QUADRANT, AND THE MOVEMENT OF THE LEVERS WAS STIFF. THE THROTTLE, PROPELLER CONTROL, AND MIXTURE LEVERS WERE VERY CLOSE TOGETHER, AND MOVEMENT OF ONE LEVER WOULD CAUSE RUBBING ON THE LEVER NEXT TO IT. THE QUADRANT HOUSING HAD EVIDENCE OF THE LEVERS RUBBING ON THE BOTTOM OF THE HOUSING. THE MIXTURE LEVER SHOWED EVIDENCE OF EXTENSIVE WEAR AND ELONGATION OF THE ATTACH HOLE. THE CABLE ATTACH HOLE WAS WORN COMPLETELY THROUGH THE END OF THE LEVER, AND THE MIXTURE CABLE WAS NOT ATTACHED.
