Probable cause

The pilot’s failure to maintain adequate clearance during landing on a rooftop helipad.

Findings · 1

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that he was on approach to a hospital rooftop helipad that he had never landed at before. About 30 ft above ground level, he felt a “thump” in the pedals; the helicopter vibrated, pitched forward, rolled left, then yawed right. The pilot landed the helicopter on the helipad. After the accident the pilot discovered that the tail rotor had contacted the building. The helicopter sustained substantial damage to the tail rotor, tail rotor drivetrain, and tail pylon. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
