The FAA issued an airworthiness directive [AD 2014-03-11] on February 19 for Bell 204B helicopters requiring an inspection of the tail-rotor cable assembly for an incorrectly machined body. This AD was prompted by a report from Bell that a defective body on the cable prevents the barrel assembly from fully engaging in the body cavity. The AD, which becomes effective on March 26, is intended to prevent disengagement of the cable from the barrel, failure of the tail-rotor pitch control and subsequent loss of control of the helicopter.
