Analysis

During an IFR flt at night, the plt encountered light rime icing conditions and was cleared to dscnd from 7000 ft to 5000 ft MSL. About 14 min later, he rprtd that an eng power loss had occurred and that he was unable to maintain altitude. While being vectored to a nearby arpt, the acft collided with a 112 ft ham radio tower, about 60 ft AGL, then crashed. Witnesses rprtd the eng was at idle power during impact. During an investigation of the acdnt, no preimpact part failure, fuel contamination or verification of structural ice was found. The ham radio tower was not equipped with an identification light, nor was there a requirement for it to be lighted.
