Analysis

The commercial certificated pilot was positioning the helicopter from a private landing area to a local airport for fuel under Title 14, CFR Part 91. He said approaching the taxiway, about 20-30 feet in the air, he spotted the light atop a 20-foot light pole through the left chin-bubble. He reported that he attempted to avoid the light, but the helicopter struck the light pole, damaging the chin-bubble and associated fuselage structure. He reported there were no preaccident mechanical anomalies with the helicopter prior to the accident.
