The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A300 series airplanes. This proposed AD was prompted by a report that bleed and air conditioning systems were contaminated by hydraulic fluid, and an investigation revealed that hydraulic fluid contaminations caused the failure of check valves installed on the hydraulic reservoir air pressurization system. This proposed AD would require repetitive functional tests of the hydraulic reservoir air pressurization lines and repair or replacement, if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
