What this AD requires

We are adopting a new airworthiness directive (AD) for various Airbus Helicopters Deutschland GmbH (Airbus Helicopters) Model MBB- BK117 and Model BO-105 helicopters. This AD requires removing the swashplate bellows (bellows) and repetitively inspecting the swashplate assembly. This AD was prompted by reports of loose and missing clamps installed on bellows. The actions of this AD are intended to detect and prevent an unsafe condition on these products.

Repetitive inspection. Re-inspect every 400 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Helicopters with an MBB-BK 117C-2e designation are considered Model MBB-BK 117C-2 helicopters for purposes of this AD.

Whether AD 2019-07-07 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 2019-07-07 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.
