Analysis

A Hughes helicopter was damaged when it lost power during takeoff and was crashed into a tree to prevent it from rolling down a hill. The weather was VMC and no flight plan was filed. The pilot said the manifold pressure decayed FROM22 inches to 18 inches and rotor RPM began to bleed off. The pilot tried to regain manifold pressure by reducing collective but was unsuccessful. Density altitude was 8,800 feet. No discrepancies, other than impact related, were found during an inspection of the engine.
