Our Story

For over 30 years, Jet Support Services, Inc. (JSSI), has been the leading independent provider of maintenance support and financial services to the business aviation industry. JSSI offers hourly cost maintenance programs to manage the often unpredictable costs of operating virtually all makes and models of aircraft, engines and auxiliary power units (APUs). The company is responsible for maintaining in excess of 2,000 business jets, turboprops, regional jets and helicopters across the globe and serves customers through its unique infrastructure of expert technical advisors.

JSSI Parts & Leasing sells aircraft parts, provides lease engines and APUs, and offers supply chain solutions as a service to large fleet operators. JSSI Advisory Services and Conklin & de Decker harness this technical experience and global reach to power a complete range of consulting and digital services utilized by operators, aircraft brokers, and service providers across the industry.
