Abstract
We are adopting a new airworthiness directive (AD) for all Eurocopter France EC130B4 helicopters that have not had Eurocopter Modification 073880 incorporated. This AD is prompted by several reports of cracks in the tailboom/Fenestron junction frame, which could result in structural failure of the tail boom, resulting in detachment of the Fenestron (tail rotor) and subsequent loss of control of the helicopter. We are issuing this AD to correct the unsafe condition on these helicopters.
