Analysis

Earlier in the day the plt returned from a flt after experiencing a rough running eng & changed the spark plugs. The acft again departed the chena marina arpt. Witnesses observed the acft level off approximately 300 to 350 ft AGL. One witness observed the acft pitching up & down erractically as it leveled off. The acft then entered a right bank & was rolling out after a 90 deg heading change when the eng sputtered & quit. The nose of the acft dropped & the acft fell in a nearly vertical attitude. Eng examination revealed evidence of water & rust contamination in the carburetor & fuel pump. It is estimated that the acft was 379 pounds over max gross weight & the aft CG exceeded by 1.3 inches.
