Cessna Aircraft is adding three maintenance trucks to its international ground-based mobile service unit (MSU) fleet serving Citations across North America and Europe. The latest mobile additions to the Citation Service Center support network become active this month. One unit is positioned at Centennial Airport’s Tac Air facility near Denver. A second unit is located at Montgomery Aviation at Indianapolis Executive Airport to serve Indiana and parts of Michigan, Ohio, Illinois and Kentucky. The third, the first European MSU, will be positioned at Aéroport de Lyon-Bron to cover southern France, northern Spain, northern Italy and Geneva. “We have eight in the U.S. and they have done some 900 visits so far this year,” a spokesman for the company told AIN. “The object is to augment the service center so we base them at FBOs in cities apart from service centers.” The trucks carry most of the tools and equipment found in Cessna Citation Service Centers and can handle procedures up to and including Citation X engine exchanges.
