Analysis

During a flt from reno, NV to phoenix, AZ, there was a partial power loss in the left eng as the acft was climbing thru 15,000 ft with an outside air temp of -15 deg. The fuel selectors could not be moved, so the plt retarded the right eng power & descended. The left eng continued to run rough, so he diverted & landed at the Death Valley arpt. About 1/2 hr after landing, the fuel selector could be moved. The plt said he drained the fuel tanks until the engs ran smoothly. He then loaded his passengers & started both engs. While taxiing to takeoff, the left eng lost power & would not restart. The passengers deplaned & then the plt made a single eng takeoff. After the acft became airborne, it climbed briefly, then began turning to the left. After turning about 130 deg, the acft impacted the ground between 2 sand dunes. Water was found in the left eng servo & right main fuel sump. A small amount of water was found mixed with fuel in the main tanks.
