PRODUCT: All Eurocopter Deutschland GmbH (ECD) Model EC135 helicopters, except the EC 135 P2+ and T2+.
SUBJECT: Airworthiness Directive 2012-23-07
ACTION: Final Rule
SUMMARY: This AD requires inspecting each upper and lower plain journal bearing (bearing) and replacing the swashplate assembly with an airworthy swashplate assembly if a bearing is not correctly positioned. This AD was prompted by two reports of the bearings moving in relation to the main rotor swashplate sliding sleeve (sliding sleeve).
The actions of this AD are intended to detect shifting of the bearing, which could limit the movement of the collective control and result in subsequent loss of control of the helicopter.
DATES: This AD is effective January 11, 2013.
