Upon further examination and consulting with the manufacture of the helicopter, by the operator, it was determined that a major repair was required to return the helicopter to airworthiness condition. The forward bulkhead, forward bulkhead skin, and doublers for that area of the tailcone had to be replaced. On the questionnaire submitted to the manufacture by the operator to aid in assessing the type of repair required stated "damage was sustained during a hovering autorotation." On December 3, 2004, an inspector from the FAA notified the NTSB of the damage. On December 8, 2004 a completed Pilot/Operator Aircraft Accident Report was provide by the instructor pilot who flew the helicopter the day before the damage was discovered.
