Bell 206B III accident near South Carver, Massachusetts, July 1, 1996
On July 1, 1996 at about 10:00 am local time, a Bell 206B III (helicopter), registered N444JB, was substantially damaged in an accident near South Carver, Massachusetts. It was an aerial application (crop spraying) flight under agricultural flying rules (Part 137). No one was hurt; 1 person was on board or involved. The weather was instrument conditions (cloud, fog or low visibility).
The NTSB's probable cause their words, unchanged
The pilot's failure to maintain control of the helicopter during an aerial application maneuver. This put the helicopter in a low slow down wind, high power demand turn, where it encountered a loss of tail rotor effectiveness, and the subsequent collision with the marsh.

The NTSB's narrative final · quoted from the NTSB record
The pilot was doing aerial spraying of a cranberry bog, and had completed four passes before he executed a right turn to the north to begin the next run. After completing the turn, the helicopter began to spin to the right. After about three to four turns it stopped in a level hover, but then started spinning again to the right. After another three to four spins, it again stopped, and began a final spin to the right when it collided with the bog. Bell Helicopter Textron (BHT) published an Operations Safety Notice, in 1983, which dealt with unanticipated right yaw of the Bell 206 series. It stated that unanticipated right yaw could occur when maneuvering between hover and 30 MPH, and that a tail wind could reduce relative wind speed if a down wind translation occurred. It also stated that a loss of translational lift could result in a high power demand and an additional anti-torque requirements, which included high power demand situations such as low speed downwind turns. A local automated weather report indicated that the winds from were from 210 degrees at 6 knots. The pilot stated that the uncontrolled event initiated when he had completed a right hand application turn, and did not report a lateral cyclic displacement during the last application run.
