Lampson Field Airport
Aircraft Accident/Incident Report

Lakeport, California 95453
Saturday, December 14, 1996 16:45 PST

NTSB Narrative Summary Released at Completion of Accident

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.

NTSB Probable Cause Narrative

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.
