Abstract
This amendment supersedes an existing airworthiness directive (AD) for the specified Eurocopter France (ECF) model helicopters. That AD currently requires replacing each affected unairworthy main rotor head torsion tie bar (tie bar) with an airworthy tie bar and revising the limitations section of the maintenance manual by adding a life limit for certain tie bars. This amendment requires additional revisions to the limitations section of the maintenance manual by further reducing the life limit for certain tie bars. This amendment is prompted by an accident involving an ECF Model SA341G helicopter due to the failure of a tie bar. The actions specified by this AD are intended to prevent failure of a tie bar, loss of a main rotor blade, and subsequent loss of control of the helicopter.
