Airworthiness Directives; Airbus Helicopters Deutschland GmbH (AHD) Helicopters

What this AD requires

The FAA is superseding Airworthiness Directive (AD) 2014-13- 09, which applied to certain Airbus Helicopters Deutschland GmbH (AHD) helicopters Model EC135P1, EC135P2, EC135P2+, EC135T1, EC135T2, and EC135T2+ helicopters. AD 2014-13-09 required repetitive visual inspections of the ring frame X9227 for a crack, and if there is a crack, replacing the ring frame. Since the FAA issued AD 2014-13-09, AHD Helicopters determined that this unsafe condition also applies to AHD Model EC135P3 and EC135T3 helicopters. This AD continues to require some of the actions required by AD 2014-13-09 and expands the applicability by including AHD Model EC135P3 and EC135T3 helicopters and also reduces the compliance time for the repetitive inspections. This AD also allows the modification of the ring frame X9227 as terminating action for the repetitive visual inspections. The FAA is issuing this AD to address the unsafe condition on these products.

Repetitive inspection. Re-inspect every 25 hours. The next-due date/hours depend on this aircraft’s time in service — a records report computes it from the logbooks.

Part-conditional — L535H2120301, L535H2120303, L535H2120304.

Applies only to helicopters with mounting ring frame X9227, P/N L535H2120301, L535H2120303, or L535H2120304 installed; excludes helicopters with frame reinforcement P/N L535H2100201 or L535H2100202 installed. Helicopters with an EC135P3H designation are considered Model EC135P3, and helicopters with an EC135T3H designation are considered Model EC135T3.

Whether AD 2026-01956 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 2026-01956 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.
