What to do
Operators of affected Airbus Helicopters H160-B with specified serial numbers must complete the required software modifications within three months of the directive's effective date. They must also upgrade the Engine Electronic Control Unit software prior to or concurrently with these modifications. Additionally, the rotorcraft flight manual must be amended before the next flight after modification, and ongoing operational checks must be performed as specified.
Summary
EASA Airworthiness Directive 2023-0139 is an amendment addressing Airbus Helicopters H160-B models with specific serial numbers. It mandates modifications to the rotorcraft flight manual and avionics software to enhance system integration and display reliability. The directive targets software updates and operational checks to mitigate risks associated with Multi-Function Display failures.
What changed
This directive requires the concurrent upload of updated software for the Aircraft Management Computer, Multi-Function Displays, and Dynamic Monitoring Acquisition Unit, along with an upgrade of the Engine Electronic Control Unit software. It also mandates amendments to the rotorcraft flight manual and introduces new repetitive operational checks for the aircraft management computer. These changes build upon previous interim actions and do not supersede earlier directives.
Why it matters
The directive addresses a critical safety issue where Ethernet network management deficiencies could cause multiple display failures, potentially reducing pilot situational awareness and helicopter control. Compliance ensures enhanced avionics robustness, reducing the risk of in-flight system failures. Operators and maintenance organizations must implement these updates to maintain airworthiness and regulatory compliance.
