NTSB narrative
While in a descent from cruise flight the engine sustained a total loss of engine power, resulting in a forced landing to a shoreline consisting of soft sand. A post accident examination of the engine revealed connecting rods 2, 3, 4, 5 and 6 were separated from the crankshaft. There was also evidence of connecting rod bearing heat stress and lack of lubrication, metal observed in the oil pan, and four penetrating holes in the bottom of the crankcase. Prior to preparing the engine for teardown only about one quart of oil was drained from the oil sump. The engine had accumulated a total of 1,956 hours since its most recent major overhaul; recommended time between overhauls is 2,000 hours. The pilot reported fuel and oil levels were normal for the flight and that no anomalies were noted, which would have precluded normal operation.
Probable cause
A lack of lubrication for undetermined reasons, which resulted in the failure of the Nos. 2, 3, 4, 5 and 6 connecting rods, a subsequent total loss of engine power during descent, which resulted in a forced landing. A factor in the accident was the soft sand.

- 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.
