Probable cause
A loss of engine power for undetermined reasons. A factor related to the accident was: the lack of a suitable area for an emergency landing.
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 reported that the Hughes 369D was cruising between 300 and 500 feet above the surface, when he heard a loud 'pop' and the engine spooled down rapidly. He stated that he had no previous indication of a problem until the engine abruptly lost power. He initiated an autorotation and landed on a sloped portion of the highway. After touchdown, the right skid dropped approximately 20 inches and the main rotor blades struck the tailboom. No preimpact mechanical discrepancy was found.
