What to do
Operators of Airbus Helicopters EC 175 B with Helionix v11 or v11.1 avionics must incorporate the Rotorcraft Flight Manual update within 30 days after the effective date of the directive. They must cease using the assisted take-off modes of the Automatic Flight Control System from that time. Compliance can be achieved by amending the RFM with the specified update documents.
Summary
EASA Airworthiness Directive Proposal PAD No. 26-134 is an amendment concerning Airbus Helicopters EC 175 B models equipped with Helionix v11 or v11.1 avionics suites. It addresses changes to the Rotorcraft Flight Manual – Limitations and Normal Procedures Section. The directive proposes operational limitations related to the Automatic Flight Control System during one engine inoperative scenarios.
What changed
The proposed amendment prohibits the use of the 'assisted take-off modes' in the Automatic Flight Control System for the EC 175 B helicopters. This change is introduced through an update to the Rotorcraft Flight Manual, which includes new operational limitations and procedures to mitigate unsafe helicopter behavior during one engine inoperative conditions with assisted take-off mode selected.
Why it matters
This amendment is critical for aviation professionals as it addresses a potential safety risk that could lead to collisions with the ground or water during take-off under engine failure conditions. Operators, maintenance, and compliance teams must ensure that the new limitations are incorporated to maintain airworthiness and operational safety. Failure to comply could result in unsafe flight conditions and regulatory non-compliance.
