Airworthiness Directives; Eurocopter Deutschland GmbH Helicopters

What this AD requires

We are adopting a new airworthiness directive (AD) for Eurocopter Deutschland GmbH (ECD) Model EC135 and MBB-BK 117 C-2 helicopters. This AD requires inspecting the flight-control bearings repetitively, replacing any loose bearing with an airworthy flight- control bearing, and installing bushings and washers. This AD was prompted by the discovery during a routine inspection of loose flight control bearings because of incorrect installation. The actions of this AD are intended to prevent the affected control lever from shifting, contacting the helicopter structure, and reducing control of the helicopter.

Repetitive inspection. Re-inspect every 800 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Serial-conditional — narrows to serials 0005–00829, 9004–9310.
Part-conditional — L672M2802205, L672M1012212, L671M1005250, L671M2020108, L671M5040207, B672M1007101, B672M1807101, B672M1002202.

Applies only when specific flight control levers/plates are installed and incorrectly-installed bearings are present. EC135 models (S/N 0005 through 00829) apply when fitted with tail rotor control lever P/N L672M2802205 or L672M1012212, cyclic control lever P/N L671M1005250, collective control lever assembly P/N L671M2020108, or collective control plate P/N L671M5040207. MBB-BK 117 C-2 (S/N 9004 through 9310) applies when fitted with tail rotor control lever assembly P/N B672M1007101 or B672M1807101, tail rotor control lever P/N B672M1002202 or L672M2802205, or lateral control lever assembly P/N B670M1008101.

Whether AD 2014-05-06 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2014-05-06 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
