NTSB narrative
The sport pilot was conducting a cross-country flight when the experimental amateur-built airplane experienced a loss of engine power; the pilot then conducted a forced landing to a field, and the airplane sustained substantial damage. Postaccident examination of the airplane revealed a broken wire to the airplane's alternator; this specific wire supplied electrical power to the alternator field coil. Because the wire was broken, the alternator was rendered inoperative. The pilot would not have been able to detect the broken alternator wire without removing the engine cowl, which is not normally part of a pilot's preflight examination.
The airplane's engine had been modified to use an ignition system that operated from the airplane's electrical system, which included a battery and the alternator to maintain the battery's charge. Once the alternator field wire had broken, the ignition system relied completely on the airplane battery's reserve power as the source of ignition power. Once the battery power was depleted, the ignition system could not operate, and the engine lost power due to the lack of ignition.
Probable cause
The loss of engine power due to a lack of ignition resulting from a broken alternator wire.

- 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, coordinates. 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.
