## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

WHILE PERFORMING FLIGHT INSTRUCTION IN N2686, THE PIC LOST DIRECTIONAL CONTROL OF THE AIRCRAFT.  THIS LOSS OF CONTROL RESULTED IN DAMAGE TO THE HELICOPTER TAIL BOOM AND TAIL ROTOR BLADE.  NO INJURIES TO AIRCRAFT OCCUPANTS OR PERSONS ON THE GROUND.  NO DAMAGE TO PROPERTY AND NO POST-CRASH FIRE.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
