Analysis

The plt stated there were mechanical problems with the acft but it was decided to fly it back to another arpt for repairs. Enroute the plt shut down the right eng because of an oil leak. While attempting to crossfeed fuel, the plt accidently pushed the left eng fire wall fuel shut off valve which resulted in a loss of pwr on the left eng. The acft was substantially damaged during the forced landing on rough tundra.
