What to do
Operators of affected Airbus A330 models must modify or replace the three FCPCs with the specified software standards within 12 months after 25 December 2017. After modification, certain AFM temporary revisions related to AOA sensors can be removed if the aircraft configuration matches those listed. Installation of earlier software or hardware versions than those specified is prohibited from 25 December 2017 onward.
Summary
EASA Airworthiness Directive 2017-0246R1 is an amendment addressing Airbus A330 series aeroplanes equipped with specific Flight Control Primary Computer (FCPC) software and hardware versions. It mandates modification or replacement of FCPC software to newer standards to enhance Angle of Attack (AOA) blockage detection and improve flight safety. The directive also updates operational procedures related to the Aircraft Flight Manual (AFM) emergency revisions for certain AOA sensor configurations.
What changed
EASA Airworthiness Directive 2017-0246R1 revises the original AD 2017-0246 by introducing new FCPC software standards (P15/M24, P16/M25, M25) developed through Airbus modifications 206412, 206413, and 206414. It expands the scope of AFM emergency procedure removals for additional AOA sensor and FCPC configurations and updates compliance requirements accordingly.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk related to undetected AOA blockages that could lead to unintended Alpha protection activation and reduced aircraft control. Operators and maintenance teams must ensure FCPC software is updated to prevent potential flight control issues and maintain regulatory compliance. Removing outdated AFM emergency procedures also streamlines operational documentation and procedures.
