BERLIN — The European Aviation Safety Agency recommended Tuesday that companies stop procuring materials from Kobe Steel Ltd., which is embroiled in a data falsification scandal, until the safety of its products is confirmed.

The agency said in a statement it had advised companies that use Kobe Steel products to thoroughly review their supply chains to determine if affected materials had been used. The recommendation was made “until further information becomes available, allowing refinement of the scope of the problem and determination of its potential significance to safety.”

The agency also advised concerned parties to report to relevant authorities about the use of such materials and access alternative suppliers “until the legitimacy of the affected parts can be determined.”

Kobe Steel has said it shipped materials for which data had been falsified to about 500 companies, with its products used globally in cars, trains, airplanes and defense equipment. Nissan Motor Co., Honda Motor Co. and Mitsubishi Heavy Industries Ltd. as well as major Japanese railway companies are among businesses that used the affected materials.

General Motors Co., Ford Motor Co., Airbus and Boeing Co. are also reportedly investigating whether they used any of the materials.

Kobe Steel has also been asked by the U.S. Justice Department to submit documents related to the data fabrication scandal, as the company supplies products to a wide range of industries in the United States.
