Crashed into sea following loss of tail rotor control. A tail rotor control cable had been routed over a stainless steel grommet in the area of pulleys (2) under the Main Gear Box. The bracket holding these pulleys did not allow for visual confirmation of the routing. With a broken tail rotor control cable at that time, the tail rotor went immediately to full pitch, a condition from which a recovery was not possible.

A self centering device like that of the H-60 was later added which, under the same circumstances, would result in the T/R centering allowing a run-on landing to be performed. In September 1983 a US-registered S-76 (N-521AC) ditched in Lake Michigan following loss of tail rotor control.
