What this AD requires

We are adopting a new airworthiness directive (AD) for all Eurocopter Deutschland GmbH (ECD) Model EC135 helicopters, except the EC 135 P2+ and T2+. 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.

MakesEurocopter

ModelsEC135

Part-conditional — L623M2006101.

Applies to all EC135 models except EC135 P2+ and EC135 T2+, and only when swashplate assembly P/N L623M2006101 is installed.

Whether AD 2012-28044 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 2012-28044 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.
