Read the full NTSB narrative

The pilot was leaving Green Bay, Wisconsin for the return flight to Rockford, Illinois. On the preflight inspection, the pilot said he noticed that the right auxiliary tank was overfilled, but did not worry about it. When he attempted to start the right engine, the right wing exploded. The airplane had recently been painted. During the painting process, both wings had been removed and replaced. The investigation revealed the fuel vapor return lines for the main and auxiliary tanks in the right wing had been reversed, and that the vent for the auxiliary tank had been disconnected, allowing the auxiliary tank to vent to the interior of the right wing.
