Jenner & Block Secures DC Circuit Victory for Client Adacel Systems
News
July 27, 2026
Jenner & Block secured a win before the US Court of Appeals for the District of Columbia Circuit on behalf of client Adacel Systems, Inc., successfully defending an FAA contract award against a challenge brought by a competing contractor.
The dispute concerned the FAA's decision to award Adacel a contract to modernize the hardware behind the agency's systems used to train air traffic controllers at facilities nationwide. Adsync Technologies, the program's longtime incumbent contractor, challenged that award before the agency and, after the FAA's decision was upheld, petitioned the DC Circuit for review. Adacel intervened in support of the FAA on appeal, and the court ruled in Adacel's favor.
The result allows Adacel to continue its work modernizing critical air traffic control training infrastructure and underscores the deference federal courts continue to afford agencies' technical and procurement judgments on review.
Partner Liz Deutsch argued the appeal and led the team alongside Partner Noah Bleicher, with support from associates Maura Smyles and Jennifer Retener.
