The European Aviation Safety Agency (EASA) issued a directive concerning a potential failure of the Airbus A350 cooling system, which could lead to overheating and fire in the fuel tanks. Airbus has warned airlines and is preparing a software update for all A350-900s that are in service.
The "Emergency Airworthiness Directive" (EAD) dated 22 August 2017 and, which is effective since August 22, 2017, concerns precisely the possible failure of the EDP (Engine Driven Pump) that could lead to rapid overheating of the hydraulic fluid of the cooling system located in the fuel tanks of the A350 series.
Airbus said that a software should be ready in the coming weeks to mitigate any risk of malfunction.
If not detected and corrected, the problem could lead to uncontrolled overheating of the hydraulic fluid and possible ignition of the fuel-air mixture in the tank. EASA says Airbus has published a Major Event Revision for the A350s, incorporating restrictions to avoid uncontrollable overheating of the hydraulic system.
Airbus said that a software should be ready "in the coming weeks to mitigate any risk of malfunction.
