Jet Maintenance International (JMI) has received an authorized service center designation from Williams International for the FJ44 engine variants that power Cessna Citation CJ-series twinjets. The appointment follows technician training on the FJ44 at Williams’s headquarters in Michigan, as well as a $120,000 investment in tools and inventory at JMI’s London Oxford Airport facility.

JMI has dedicated space inside a 16,000-sq-ft hangar at London Oxford for the FJ44 MRO activity. The authorization builds on the line maintenance support for Citations that the company offers at London Oxford and Biggin Hill airports. It also comes after JMI received FAA repair station approval to provide maintenance on U.S.-registered Citations.

“Now we can offer our European Cessna Citation customers a one-stop with aircraft and engine MRO and Tamarack active winglets installations, too,” said JMI director Ed Griffith. The company is also working to expand its mobile service units for AOG support from London Oxford and Biggin Hill.
