A court in the south German city of Munich began on Monday hearing the case of an Austrian man suspected of spying for Russia, local media said.
Harald Alois, 52, was arrested on May 27 for providing Russia's Foreign Intelligence Service with technologies developed by the global helicopter manufacturing firm, Eurocopter.
He allegedly received around $10,500 for the work, carried out between 1997 and 2002.
A spokesman for the prosecutors said Alois could face a fine or a prison sentence of up to five years if found guilty.
