Maintenance specialist Lufthansa Technik has appointed Thomas Kuhn to replace Manfred Gartner as chief executive of its US-based VIP completion centre BizJet International.

Kuhn has been director of engineering services for the VIP completions division at the MRO group's Hamburg base since 2011.

Gartner took over responsibility for Tulsa-based BizJet in 2013. He will leave his post at the end of this month to pursue a career outside Lufthansa Group, the maintenance provider says.
