What to do
Operators of affected Airbus A330-200 series aeroplanes must upgrade the FCPC to the specified standard within 12 months after the directive's effective date. They must also verify and implement all concurrent modifications as outlined in the directive before or during the FCPC upgrade. Additionally, updated maintenance and repair instructions must be followed post-modification, and only serviceable FCPC units may be installed thereafter.
Summary
EASA Airworthiness Directive Proposal 26-108 is a regulatory document addressing Airbus A330-200 series aeroplanes, specifically models A330-201, A330-202, A330-203, A330-223, A330-223F, A330-243, and A330-243F with manufacturer serial numbers up to 2164. The directive focuses on modifying the Flight Control Primary Computer (FCPC) to a new standard to prevent faults affecting critical flight control systems. This proposal aims to enhance flight safety by mandating upgrades to the FCPC system on affected aircraft.
What changed
This new proposed Airworthiness Directive introduces a mandatory upgrade of the Flight Control Primary Computer to standard P19/M24A 2K2 for Group 2 and Group 3 Airbus A330-200 series aeroplanes. It requires compliance with specific Airbus Service Bulletins and concurrent modifications to ensure proper installation and functionality. The directive also imposes updated maintenance and repair procedures following the modification.
Why it matters
This directive is crucial for aviation professionals as it addresses a safety issue where a triple primary fault at touchdown could lead to loss of ground spoilers, thrust reversers, and auto-brake systems, potentially reducing aircraft control. Operators and maintenance organizations must comply to prevent similar incidents and ensure continued airworthiness. Compliance ensures that aircraft systems operate reliably, maintaining safety standards and regulatory compliance.
