NTSB narrative
The pilot of the experimental, amateur-built airplane stated that the airplane sustained a total loss of engine power during the departure climb. The pilot then performed a forced landing on a field near the departure end of the runway. During the landing, the airplane’s landing gear dug into soft terrain resulting in a nose over of the airplane. The airplane sustained substantial damage to both wings.
Postaccident examination revealed the airplane was equipped with a supplemental ignition system. Two units of the supplemental system were installed with fuses that were not called for in the system installation instructions. One of the fuses was blown, which disabled one of the two units and did not allow for the airplane’s magneto system to continue providing engine ignition, resulting in a total loss of engine power.
Probable cause
The improper installation of the supplemental ignition system, which resulted in a total loss of engine power.

- 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, cause areas. 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.
