NTSB narrative

WHILE IN CRUISE FLT, PLT NOTED GRADUAL LEFT ENG OIL PRESS DROP FROM NORMAL 70 PSI TO 20 PSI. PLT SHUT DOWN LEFT ENG, FEATHERED PROP AND DIVERTED TO ALTERNATE AIRPORT. EN ROUTE TO ALTERNATE PLT ATTEMPTED TO RESTART LEFT ENG TO AVOID SINGLE-ENGINE LANDING. PLT STATED ACFT BATTERY WAS 'GROUND DOWN' BY UNSUCCESSFUL START ATTEMPTS. ON ARRIVAL AT AIRPORT, GEAR WOULD NOT LOWER BY ELECTRICAL SYSTEM DUE LOW BATTERY OUTPUT. PLT ATTEMPTED TO LOWER GEAR MANUALLY BUT INSUFFICIENT TIME AND ALTITUDE REMAINED TO COMPLETE OPERATION BEFORE LANDING. PLT ATTEMPTED SINGLE- ENGINE GO-AROUND WITH GEAR PARTIALLY EXTENDED. ACFT WOULD NOT MAINTAIN ALTITUDE. PLT EXECUTED FORCED LANDING IN OPEN FIELD, ELEVATION 5600 FT MSL.

  • 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.
