Analysis

The acft was on its first flight in about 2 years when the accident occurred. The acft was being flown to the destination where it was to be used for salvage. According to the pilot, while en route, the right engine began running rough before it lost total power. The plt said he was unable to maintain altitude on the other engine, so he did a forced landing on a highway where the acft struck a truck. The examination of the engine revealed the right engine air filter was obstructed.
