Analysis

The acft experienced a double eng failure as a result of fuel exhaustion during descent to the destination aprt. The plt attempted to divert to a nearby arpt during the descent, but both engs quit before he had the rwy assured. The subsequent attempted forced landing resulted in substantial damage when the left eng restarted during the flare and spun the acft around to the right. The right wing tip struck the ground, yawing the acft on touchdown. All 3 landing gear collapsed as a result of side loads. The plt stated that adverse winds aloft extended the flt and prevented him from arriving at the destination arpt and that when he became aware of the critical fuel state, it was too late.
