Summary
EASA Airworthiness Directive 2021-0127 is an official regulatory document addressing Airbus A350-941 and A350-1041 aeroplanes. It mandates modifications to the landing gear management system software to ensure continued airworthiness and safety. The directive applies to all serial numbers except those with Airbus modification 114420 already incorporated in production.
What changed
This directive introduces a requirement to update the Braking Control System, Wheel Steering Control System, and Landing Gear Extension and Retraction System software to new serviceable standards. These software updates correct previously identified monitoring deficiencies that could reduce braking performance under certain degraded conditions. The directive requires installation of these updated software versions within a specified timeframe.
Why it matters
The software updates mandated by EASA Airworthiness Directive 2021-0127 are critical to maintaining safe braking performance and preventing runway excursions. Compliance ensures that operators mitigate risks of damage to aircraft and injury to occupants. Maintenance and compliance teams must prioritize these updates to meet regulatory requirements and uphold operational safety standards.
