Action
Final rule.
Summary
We are revising airworthiness directive (AD) 2015-12-09 for Airbus Helicopters Model EC135P1, EC135T1, EC135P2, EC135T2, EC135P2+, EC135T2+, and MBB-BK 117 C-2 helicopters. AD 2015-12-09 required inspecting certain washers for movement and making the appropriate repairs if the washers move. As published, AD 2015-12-09 referenced an incorrect date for the service information in the Credit for Previous Actions section. This AD corrects the error while retaining the requirements of AD 2015-12-09. These actions are intended to prevent loss of concerned control axis and subsequent loss of control of the helicopter.
