Analysis

Enroute in IMC the acft had a complete electrical failure. The plt descended to VFR conditions & elected to land at weiser arpt. The plt lowered the gear electrically but did not receive a green down & locked indication. He then pumped the emergency extension handle but still did not get a green down & locked indication. The main gear retracted during the landing. Had the plt continued to manually pump he would have locked the gear down. The alternator fan blade had separated & exited through the eng cowling. The resultant vibration caused the alternator ground wire to separate from its attach point causing the total electrical failure.
