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.

Operation was for the repair of a fiber shoe that supports a fiber optic line that was attached to a tower about 200' above the ground. The lineman on board the helicopter was hoisting the line off the shoe using a hoist especially designed for this type of operation. It is only attached to the tower structure and line. A nylon strap that is part of the hoist failed, which caused the line to drop and hit the skid of the helicopter which caused the helicopter to immediately drop and the rotor blades contacted the tower structure. The pilot then pulled away from the tower and landed the helicopter next to the tower. There was no loss of control of the helicopter after the initial failure of the hoist device and line hitting the skid.

As the FAA filed it

THE LINEMAN ON BOARD THE HELICOPTER WAS HOISTING THE LINE OFF THE SHOE USING A HOIST ESPECIALLY DESIGNED FOR THIS TYPE OF OPERATION. IT IS ONLY ATTACHED TO THE TOWER STRUCTURE AND LINE. A NYLON STRAP THAT IS PART OF THE HOIST FAILED, WHICH CAUSED THE LINE TO DROP AND HIT THE SKID OF THE HELICOPTER WHICH CAUSED THE HELICOPTER TO IMMEDIATELY DROP AND THE ROTOR BLADES CONTACTED THE TOWER STRUCTURE. THE PILOT THEN PULLED AWAY FROM THE TOWER AND LANDED THE HELICOPTER NEXT TO THE TOWER. THERE WAS NO LOSS OF CONTROL OF THE HELICOPTER AFTER THE INITIAL FAILURE OF THE HOIST DEVICE AND LINE HITTING THE SKID.
