Resumen
We are superseding Airworthiness Directive (AD) 2014-24-02 for Agusta S.p.A. (Agusta) Model AB139 and AW139 helicopters. AD 2014-24-02 required repetitively inspecting the main rotor (M/R) rotating scissors, removing certain lower half scissor spherical bearings (bearings) from service, and installing a special nut. This new AD revises the inspection requirements and requires replacing the bearings. This AD is prompted by a new report of a dislodged bearing of an M/R rotating scissor. The actions of this AD are intended to correct an unsafe condition on these products.
