Analysis

The acft was last refueled on a previous flt. At Dunsmuir, it was parked til the next week when maint was performed for a low manifold pres prblm. The owner elected to fly the acft to redding for an annual insp. He estimated there was at least 9 gals of usable fuel remaining. He then flew to redding & picked up a mechanic. The mechanic was to fly back to Dunsmuir with the plt, then rtrn the acft to redding. Bfr depg fm redding, the mechanic looked inside both fuel tanks while the eng was running & saw no fuel in the rgt tank & some fuel in the l tank. At Dunsmuir, the owner deplaned & the mechanic depd on the 15 to 20 min flt back to redding. The plt (mechanic) said the acft was climbing abt 5 mi fm the arpt when the eng quit. Atmts to get it restarted were unsuccessful. He turned back twd the arpt, but the acft crash landed short of the rwy. Only residual fuel was fnd in the fuel tanks; fuel sys continuity was established. According to the flt manual, a min of 13 gal was reqd in each fuel tank bfr takeoff.
