Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot was having cooling fan problems, some blades had broken. He landed in a canyon stayed overnight to cool engine and planned to fly to top of the canyon to get repairs. After takeoff, the helicopter had climbed almost level with the top of the canyon when the engine failed. During an emergency landing, the helicopter hit the tops of 3 trees, then crashed on its top. An examination of the cooling fan revealed that it was worn, had reworked parts, contained incorrect parts, and 13 fatique cracks were found in the fan.
