NTSB narrative

According to the flight instructor (CFI), seconds before the crash, both he and his student were handling the flight controls. The CFI indicated that he had been instructing his student how to hover in ground effect when the student abruptly over controlled. The CFI took the controls from his student a 'little bit too late to correct' the student's control inputs. The main rotor blades struck the ground, and the helicopter rolled over. The CFI further reported that the ground adjacent to the crash site sloped slightly upward, and he had misjudged the location of the horizon. The CFI had been a rotorcraft flight instructor for about 2 weeks.

Probable cause

inadequate supervision by the flight instructor (CFI), and his delayed corrective action to the student pilot's abrupt control inputs, thereby allowing the main rotor blades to strike the ground. Factors relating to the accident were: the CFI's lack of instructing experience and the presence of upsloping terrain.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1996-12-15.
