Analysis

Before reaching the destination arpt, the eng lost power. The plt attempted to restart the eng, but was unable. She maneuvered to land on a roadway & remained over the median as long as possible to avoid vehicles. Drg the landing, the right wing hit a utility pole next to the curb of the roadway & the wing was torn off the acft. The acft then went down an embankment & came to rest inverted. After the acdnt, the plt rprtd the acft had run out of fuel, while the gauge of the fullest tank was indicating 1/4 full.
