Relevant A330-200 AD

Several reports have recently been received of loose pneumatic quick-disconnect unions on Goodrich pitot probes P/N (part number) 0851HL. These may be the result of mis-torque of the affected unions at equipment manufacturing level. Investigations are still on-going to determine the root cause(s).
This condition, if not corrected, could lead to an air leak, resulting in incorrect total pressure measurement and consequent erroneous Calibrated Airspeed (CAS)/MACH parameters delivered by the Air Data Computer (ADC).

Loss or fluctuation of indicated airspeed could result in misleading information provided to the flightcrew. We are issuing this AD to require actions to correct the unsafe condition on these products.
