This opportunity involves a sole-source contract for comprehensive maintenance and airworthiness support of two C-37B (Gulfstream 650ER) aircraft. The contractor will provide personnel, engineering services, and supply chain management for both scheduled and unscheduled maintenance. The urgency was driven by the government's lack of immediate infrastructure and personnel to assume maintenance after aircraft transfer, with any delay risking airworthiness and asset value. The awarded contractor had unique, immediate access to the aircraft as they were already housed alongside other DHS assets. The aircraft are essential for DHS mission requirements, homeland security, and public safety.
