What this AD requires

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters. This AD was prompted by reports of significant wear of the spherical bearings of the control rod assembly and pitch link assembly. This AD requires measuring the radial play of certain spherical bearings of control rod assemblies and pitch link assemblies, reporting the results, and depending on the results, taking corrective action. This AD also prohibits installing certain control rod assemblies and pitch link assemblies unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.

Helicopters with an MBB-BK117 C-2e designation are considered Model MBB-BK117 C-2 helicopters.

Whether AD 2025-16-02 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 complianceThe specific action taken (inspected, replaced, modified) and to what revision.
DateWhen the work was done.
Aircraft timeTotal time in service / tach at compliance — how recurring next-due is computed.
Signature & certificateThe A&P/IA who returned it to service, with certificate number.
Is AD 2025-16-02 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.
