Sheet Metal Shop - ACJ Support in Wegberg, GER

In 2012 we took over Ralf Kohnen Flugzeugreparaturen GmbH and thus extended our services with the branch in Wegberg, acquired the workshop and office equipment as part of an asset deal and finally took over all staff.

Hence it is now possible to offer you the proven services of Flugzeugreparaturen Ralf Kohnen as well as further activities, like e.g. temporary employment as part of the new business division ACJ Support. Indeed the name is different, but the standards that you know from Ralf Kohnen and his team are preserved. As the manager of our new business division Mr. Volker Busch is at your disposal. This new business division of ACC COLUMBIA Jet Service GmbH represents an ideal complement to our existing service portfolio and capacities.
