Summary

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 Freighter, -200 and -300 series airplanes; and Airbus Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports of certain hydraulic reservoirs (HRs) becoming depressurized due to air leakage from the HR pressure relief valve (PRV). This AD requires repetitive inspections of the hydraulic fluid levels and nitrogen gas pressure in the HR for each hydraulic circuit, and if necessary, adjustment of the fluid level(s) and nitrogen pressure in affected HRs. We are issuing this AD to address the unsafe condition on these products.
