NTSB narrative
The pilot stated that there was a partial loss of engine power shortly after the airplane lifted off. The airplane would not climb, so he elected to land on the remaining runway. In his attempt to avoid lights at the end of the runway, the pilot stalled the airplane approximately ten feet above the surface. The airplane impacted the runway in a steep nose down attitude, then '...rolled over onto it's back.' Postaccident investigation revealed that the #1 spark plug failed an electrical function test. The pilot stated that the spark plug operated normally under low load conditions, but '...[stopped] under full load.'
Probable cause
a partial loss of engine power due to spark plug failure, and the pilot's evasive maneuver to avoid lights at the end of the runway.

- 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.
