NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During a swath run, the acft began to lose power, so the plt aborted the mission & started back to the arpt to land. However, before reaching the arpt, the eng quit running & the plt landed in a field. During the landing, the acft was extensively damaged. An investigation revealed that the oil ring on the # 3 piston was broken, but the ring was still in the piston groove & there was no damage noted to the piston land or cylinder wall. A partial disassembly of the carburetor revealed there was aprx 2 ounces of fluid in the bowl. Apprx 1/4 of the fluid was water. Except for some soot on the spark plugs, no other discrepancies of the eng were found.
