A-350/900 airplanes: update requested to prevent risks for the hydraulic system and for the fuel tanks
Rome, Italy - In a directive effective today EASA asks for the application of the measures decided by Airbus
With a directive which is effective today EASA (European Aviation Safety Agency) requested that the on-board equipments of A-350/900 airplanes be updated according to what was decided by Airbus in the revision document that the manufacturer released on August 21, 2017. In the directive EASA underlines how the hydraulic fluid cooling system is located in the fuel tanks and points out that it has been recently observed that a failure at the hydraulic pump may cause a fast temperature rise of the hydraulic fluid. If not detected and corrected, this condition might lead -if combined with an inoperative FTIS -the Fuel Tank Inerting System (FTIS) is a system that reduces the probability of ignition of flammable materials confined inside the tank- to overheat of the hydraulic fluid and to the possible ingition of the fuel-air mixture which is present inside the tank. The directive regards all A-350/941 aircraft that have not yet accomplished the update according to the recommendations released by the manufacturer on Monday, specifications that could be revised in the future.
