NTSB narrative
IMMEDIATELY AFTER TAKEOFF THE ENG LOST POWER & THE ACFT WAS UNABLE TO MAINTAIN LEVEL FLT. THE ACFT LANDED IN SAND DUNES AND FLIPPED OVER. DURING A SUBSEQUENT ENG RUN IT WAS NOTED THAT THE ENG RAN NORMALLY AT LOW POWER SETTINGS BUT AT TAKEOFF POWER SETTINGS IT DEVELOPED AN APPARENT IGNITION PROBLEM IN THAT THE ENG MISFIRED & SURGED. INSPECTION REVEALED THAT THE RIGHT MAGNETO WAS NOT DEVELOPING SUFFICIENT VOLTAGE OUTPUT. THE RECOMMENDED SERVICE LIFE OF THE MAGNETO IS 900 HOURS & IT APPEARED THIS MAGNETO WAS IN SERVICE FOR 1897 HOURS.

Source notes (4)
- 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.
