NTSB narrative

The pilot reported that prior to taking off for the planned 10-minute-long flight both fuel tanks contained over 5 gallons of fuel, and all airplane systems were functioning normally. The pilot arrived at his destination airport and entered the traffic pattern. Carburetor heat was applied, the throttle was retarded, and the airplane descended. After turning onto the base leg the pilot moved the throttle forward to increase engine power, and the engine 'blubbered and totally lost power.' Unable to glide to the runway, the pilot made a forced landing in a soft field adjacent to the airport, and the airplane nosed over. The FAA coordinator responded to the accident site and examined the wreckage. The FAA reported it examined the powerplant, induction system, engine controls, and magnetos. The ignition switch and the carburetor were also functionally examined. No evidence was found of any mechanical malfunctions. The reason for the interruption of engine power was not determined.

Probable cause

A total loss of engine power for undetermined non-mechanical reasons. A contributing factor in the landing nose-over was the presence of the soft 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: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1998-05-15.
