Airworthiness Directives; Airbus Helicopters Deutschland GmbH Helicopters

Riepilogo

The FAA is superseding Airworthiness Directive (AD) 2007-26-51 which applied to certain Airbus Helicopters Deutschland GmbH Model EC135 helicopters. AD 2007-26-51 required inspecting the tail rotor control rod (control rod) and ball pivot and, depending on findings, replacing those parts. This new AD requires inspecting certain ball pivots, applying corrosion preventative compound on the ball pivot, and corrective action, as applicable. This AD also requires replacing the control rod with a newly developed control rod. This AD was prompted by the manufacturer's development of a new control rod, which the FAA has determined must be installed in order to address the identified unsafe condition. The actions of this AD are intended to address an unsafe condition on these products.
