Dassault Falcon Jet is weighing whether to shutter its heavy service center at New Castle Airport in Wilmington, Delaware, the French airframer told AIN. Operating from four hangar bays totaling more than 300,000 sq ft, the 21-year-old site also includes a paint shop and FBO for Falcon operators.

According to the company, there are “continuing challenges specifically facing the Wilmington facility,” and its management team met earlier this week with the site’s union representatives to discuss “steps that may need to be taken in the future.”

“Included in the list of possibilities is the orderly closure of the Wilmington-based MRO and FBO operations,” added Dassault Falcon Jet. While the company did not identify the site’s challenges, the union representing the Wilmington workers filed a case with the National Labor Relations Board earlier this year that includes an allegation of “refusal to bargain/bad faith bargaining” on the part of Dassault Falcon Jet.

Last week, the service center also issued Worker Adjustment and Retraining Notification (WARN) Notices to its MRO and FBO employees there, providing them 60-days advance notice of a potential closing. In the meantime, management and union representatives are expected to meet again in the “near future” to continue discussions. The Wilmington site will continue to operate normally in the interim, the company added.
