Probable cause

The failure of the pilot to maintain rotor RPM and the failure of the CFI to monitor the controls.

Sequence of events

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.

Airframe/component/system failure/malfunctionLanding - flare/touchdown
Misc rotorcraft,tail boom - failure,partial
Collective - improper use ofPilot in commandCause
Monitoring - inattentivePilot in command(cfi)Cause

Analysis

The instructor pilot simulated an engine failure and the pilot executed a 180-degree autorotation. During the flare and cushion the pilot allowed the rotor RPM to decay and the instructor pilot did not monitor the pilot's use of the collective pitch control. Shortly after touchdown a vibration was felt and the tailboom failed.
