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 aircraft had just discharged two passengers on the rooftop helipad and was preparing for departure. The aircraft was picked up to a hover and the tailrotor struck a heliport surface perimeter light. The tailrotor separated from the aircraft and the aircraft rotated to the right. Throttles were reduced to stop the rotation and the aircraft settled back down to the helipad. The aircraft bounced side to side and rolled off the helipad and came to rest on its left side. The pilot exited and extinguished a small fire that had started near the engine exhaust.
