We are revising Airworthiness Directive (AD) 2013-21-05 for Eurocopter Deutschland GmbH (now Airbus Helicopters Deutschland GmbH) (Airbus Helicopters) Model EC135 P1, P2, P2+, T1, T2, and T2+ helicopters. AD 2013-21-05 required an initial and repetitive inspections of certain bearings and modifying the floor and a rod. Since we issued AD 2013-21-05, we have determined that modifying the floor and rod removes the unsafe condition. This AD retains the requirements of AD 2013-21-05 but removes the repetitive inspections. The actions of this AD are intended to prevent an unsafe condition on these products.
