EASA has issued an emergency airworthiness directive for Airbus A330/A340s fitted with a certain batch of Goodrich pitot tubes, after receiving several reports of loose pneumatic quick-disconnect unions on the tubes.

EASA says the disconnect could be the result of mis-torque of the affected unions at the equipment manufacturing level, but investigations are continuing to find the root cause.

"This condition, if not corrected, could lead to an air leak, resulting in incorrect total pressure measurement and consequent erroneous calibrated airspeed/Mach parameters delivered by the air data computer," says EASA.
