NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The pilot said his helicopter was approaching a landing area, located just east of a restaurant, from the south, in night visual meteorological conditions. During the approach, the pilot could not see the lighted flag on top of the restaurant, thus he could not determine the wind direction or velocity for landing. He executed a go around and began maneuvering so that he could approach the landing area from the east. The pilot said that at the "northern most point of the go around, a tail rotor strike was felt." The tail rotor struck telephone lines along the north side of a road. The pilot immediately put the helicopter down hard into a ditch alongside the road, breaking the left skid, crushing the right skid and fuselage upward, bending and twisting the main rotor blades, and bending the tail rotor blades. An examination of the helicopter's systems revealed no anomalies.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the pilot not maintaining clearance from the telephone lines during landing. Factors contributing to the accident were the pilot not being able to see the telephone lines, the low altitude, and the dark night. Full narrative available
