NTSB narrative

The 800-hour pilot stated that while in cruise flight, he smelled "fumes", and the engine began to "shudder." But, the engine gauges indicated normal readings. The engine continued to shudder and the oil pressure dropped to zero within a few seconds, and it began to lose power. The pilot was unable to maintain altitude and performed a forced landing to a dirt field. Upon landing, the airplane rolled about 78 feet before it nosed over onto its back. External examination of the airplane revealed oil streaks over the left and right side of the engine cowling. Examination of the engine and maintenance records revealed the recently installed generator had partially separated due to the fact it had been installed improperly, which resulted in oil starvation.

Probable cause

The improper installation of the generator, which resulted in oil starvation. A factor was the unsuitable terrain.

  • 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.
