Analysis

The acft, inactive for 8 years, was being ferried to the pilots facilities for rebuild. While in cruise flt, the rt eng quit and the prop would not feather. The acft would not maint alt in that configuration and the pilot began a forced landing, during which the left eng quit. The acft impacted soft terrain, collapsing the ldg gear, and damaging the lower fuselage. The last annual inspection was in 1982. The feery permit issued for the flt expired 2 weeks before the flt. A fuel tank was changed before the flt & the pilot applied tape on the filler cap. Post accident exam of the acft fuel system revealed the left fuel tanks were empty and the rt outboard tank line was blocked. The rt outboard tank was selected when the rt eng quit.
