European safety officials have ordered checks on certain Airbus speed sensors supplied by U.S. manufacturer Goodrich, weeks after clamping down on alternative equipment from France's Thales, according to Reuters. Potentially faulty speed readings from sensors made by Thales are at the centre of investigations into the crash of an Air France A330-200 jet in the Atlantic on June 1. In an airworthiness directive dated Sept. 22, the European Aviation Safety Agency said there had been reports of loose fittings on a number of Goodrich sensors, known as pitot probes. This could be the result of "mis-torque...at equipment manufacturing level," the Cologne-based agency said. If not corrected, such a problem could lead to an air leak and false speed readings, according to the public document. The Goodrich sensors were designed for the A330 and A340. The company was not immediately available for comment. A spokeswoman for EASA, a European Union safety agency, said the problem would be "relatively easy" to address and services were unlikely to be severely disrupted. An Airbus spokesman said the checks affected a "limited batch" of sensors and these had been tracked down through their serial numbers. The number of airlines and aircraft affected was not immediately available. It is the first time Goodrich sensors have come under the spotlight since the Air France crash highlighted the occasional fragility of systems used to measure an aircraft's speed. All 228 people on board were killed when Air France flight AF447 crashed en route from Rio de Janeiro to Paris.
