What to do
Operators of affected H160-B helicopters must implement the new RFM limitations within 30 days after 22 June 2026 and complete the HELIONIX software modification within 18 months after 6 October 2026. The software update must be performed according to the Airbus Helicopters Alert Service Bulletin H160-46-20-0003. After modification, the RFM limitations introduced by the previous AD can be removed.
Summary
EASA Airworthiness Directive 2026-0184 is an amendment addressing Airbus Helicopters H160-B models with specific serial numbers. It mandates updates to the Rotorcraft Flight Manual (RFM) limitations section and requires a software modification to the HELIONIX system to enhance flight safety during one engine inoperative conditions. This directive supersedes a previous AD and introduces new software and operational limitations.
What changed
This amendment supersedes EASA AD 2026-0104 and retains its requirements while mandating the installation of HELIONIX software version 11.0.2, which includes a new Aircraft Management Computer software partition. It also requires updating the RFM with new pilot limitations for Assisted Take-Off mode in OEI conditions and provides instructions for software modification via an Airbus Helicopters Alert Service Bulletin.
Why it matters
The directive addresses a critical safety issue where unintended altitude loss was observed during flight tests with earlier HELIONIX software versions. Compliance ensures that operators mitigate the risk of deviation from intended flight paths during one engine inoperative take-offs, reducing the potential for accidents. Maintenance and compliance teams must update manuals and software to maintain airworthiness and regulatory compliance.
