Summary
We propose to supersede airworthiness directive (AD) 2014-05- 06 for certain Eurocopter Deutschland GmbH (ECD) (now Airbus Helicopters Deutschland GmbH) Model EC135 and MBB-BK 117 C-2 helicopters to correct an error. AD 2014-05-06 currently requires inspecting the flight-control bearings repetitively, replacing any loose bearing with an airworthy flight-control bearing, and installing bushings and washers. This proposed AD would require the same actions. This proposed AD results from the discovery of an error in the compliance time for AD 2014-05-06. These proposed actions are intended to prevent the affected control lever from shifting, contacting the helicopter structure, and reducing control of the helicopter.
