The NTSB's narrative final · quoted from the NTSB record

THE PILOT STATED THAT AFTER TAKEOFF, SHE NOTED THAT THE EGT WAS RISING AFTER THE AIRPLANE HAD CLIMBED TO ABOUT 700 FEET. SHE TURNED ONTO THE DOWNWIND LEG OF THE TRAFFIC PATTERN, THEN THE ENGINE LOST POWER. THE PILOT WAS UNABLE TO REACH THE AIRPORT, AND THE AIRCRAFT COLLIDED WITH TREES SHORT OF RUNWAY 33. DURING AN INSPECTION, WATER WAS FOUND IN THE FUEL SYSTEM. THE FUEL FILLER CAP SEALS AND SEATS WERE FOUND CRACKED AND DETERIORATED. THE AIRCRAFT LOGBOOK INDICATED THAT AN AIR WORTHINESS DIRECTIVE (AD 84-10-01) HAD NOT BEEN COMPLIED WITH. THIS AD ADDRESSED THE PREVENTION OF WATER CONTAMINATION DUE TO LEAKING CAP SEALS.
