Greenville, S.C. — Stevens Aerospace and Defense Systems, LLC (Stevens) is pleased to announce that they have been awarded Williams TAP Elite Authorization at three of their MRO locations. 

Stevens was previously awarded Williams’ standard TAP (Total Assurance Program) authorization earlier in 2023 and has now been upgraded to Williams’ Elite status. The existing TAP authorization allowed Stevens to perform all routine maintenance and unscheduled line maintenance and facilitate all regularly scheduled checks on Williams FJ-44 series engines. These engines can be found on a wide range of airframes including the Citation CJ series, Beechcraft Premier, as well as STC modified aircraft such as the Citation 500, 501, 550 and the Nextant/Beechjet 400XT. TAP Elite status allows Stevens to perform Hot Section inspections “on-wing” in conjunction with other maintenance, decreasing both downtime and costs. “Very few Williams authorized service centers are awarded TAP Elite status”, said Phil Stearns, Director of Sales and Marketing, Stevens Aerospace and Defense Systems. “In the end, our customers will see lower costs and increased flexibility, ultimately getting them back in the air sooner, and on their schedule”. This level of service is available at Stevens’ Greenville, SC, Nashville, TN, and Dayton, OH MRO locations as well as through its fleet of mobile services units located throughout the United States.
