Read the full 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.
