What to do
Operators of affected Airbus A340 aircraft must install the FCMC software upgrade or replace the affected FCMC within six months of the directive's effective date. After compliance, installation of older FCMC software is prohibited to ensure continued safety and regulatory adherence.
Summary
EASA Airworthiness Directive 2018-0201 is an official directive addressing Airbus A340-213, A340-311, and A340-313 aeroplanes with specific manufacturer serial numbers. It mandates a software update to the Fuel Control and Monitoring Computer (FCMC) to the 'Stage 12' standard or higher to prevent fuel starvation issues during flight.
What changed
This new directive introduces a requirement to upgrade the FCMC software to 'Stage 12' or replace the affected hardware with a serviceable unit. The update includes a new warning feature for fuel cell depletion to enhance safety and prevent multiple engine in-flight shutdowns caused by fuel starvation.
Why it matters
This directive is critical for aviation professionals because it addresses a safety risk that could lead to multiple engine failures and reduced aircraft control. Operators and maintenance teams must ensure compliance to maintain airworthiness and avoid operational disruptions or safety incidents related to fuel management.
