From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

The pilot, privacy data omitted was getting ready to sling load a box full of core samples from a remote area northeast of Kobuk Alaska. As he lifted off and hovered, he kept an eye on the sling to ensure it was not caught on either skid. He was approximately 12 inches off the ground and noticed he was moving to the right. He felt the right skid bump the ground. He applied more collective to gain some altitude. As soon as he applied more collective the helicopter rolled to the right causing the main rotor to impact the ground. The helicopter had flipped completely onto its right side. The pilot sustained minor injuries.
