## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A319-131, -132, and -133 airplanes, Model A320-231, -232, and -233 airplanes, and Model A321-131, -231, and -232 airplanes. This proposed AD was prompted by a report of rupture of a hydraulic reservoir air pressurization hose on an in-service airplane, leading to air leakage that was undetectable during normal operation, and found during subsequent zonal inspection. This proposed AD would require modifying the airplane by replacing the affected bleed air hoses with a modification of hydraulic pressurization lines, 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.
