NTSB narrative
The 1,622-hour private pilot reported that his single-engine airplane was on a cross-country flight in cruise flight at an altitude of 3,500 feet when he heard a "metallic" noise followed by a loss of oil pressure, and oil spray on the windscreen. Shortly after, he observed smoke before the engine lost power. The pilot executed a forced landing to a state highway; however, just before touching down, a gust of wind pushed the airplane off the highway and it collided with a ditch and a fence. Examination of the engine revealed a hole in the engine case above the number 4 cylinder. Further examination revealed that the oil pressure line that was installed between an after-market oil pressure gauge and the engine had separated at the fitting where it attached to the engine. A review of the maintenance logbooks revealed that the oil pressure line was last replaced approximately 12 years earlier and had accrued approximately 412 hours at the time it failed. There was no entry in the logbook indicating when the new (and larger) oil pressure gauge had been installed.
Probable cause
The loss of engine power due to oil starvation as a result of a broken oil pressure line. A contributing factor was the lack of suitable terrain for the forced 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, coordinates. 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.
