On November 11, 1996, an Enstrom F28F (registration N86214) was involved in an aviation accident near Gutherie, IL. Investigators recorded the probable cause as: the pilot's inadequate preflight preparation and not maintaining control of the helicopter during its rearward flight. A factor was the pilot's over-confidence in his personal ability. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A helicopter lifted off on its left skid, moved forward then backward, rolled left, struck a farm truck's roof with rotor blades, and crashed inverted. Wind from right rear at 15-20 mph.
Accident Details
Witnesses observed a helicopter lift off on its left skid while moving forward a short distance. After stopping its forward motion, the helicopter began moving backwards and slowly rolling into a steep left bank while gaining altitude. After traveling about 75 feet and climbing to approximately 25 feet above ground, the helicopter moved to its left. As it passed over a farm truck, its rotor blades struck the roof. Shortly afterward, the helicopter rolled inverted and collided with the ground.
Wind Conditions
Witnesses reported the wind was between 15 and 20 miles per hour, blowing on the helicopter's right rear side.
Instructor's Comments
The pilot's former instructor stated that he had not taught the pilot to '...translate rearward.' He also said he had told the pilot it was not safe to takeoff with a quartering tailwind.
