NTSB narrative
During cruise flight, about 6,000 feet, the pilot radioed '. . . I seem to have an engine problem, I am about facing and uh looking at Weymouth Airport right now. I'm not declaring an emergency at this moment, but I do need to about face.' The controller advised the pilot that a nearby airport was closed. The pilot elected to proceed to another airport. The pilot radioed that the engine's oil pressure and temperature were '. . . in the right zone . . . .'; he later radioed 'We have no power. I have oil on the windshield.' The airplane was unable to glide to the airport. The pilot then ditched along the shore line. Examination of the engine revealed that the number five cylinder separated from the crankcase, with its mounting studs and fractured crankcase material attached. The fracture to the crankcase resulted in a 3.5 inch hole forward of the number 3 cylinder. The origin of the fracture was not determine.
Probable cause
a fracture failure of the crankcase, which resulted in separation of the number five cylinder, loss of engine power, and a ditched landing.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
