Our own global infrastructure of more than 70 certified Technical Advisors provides your appraisal team with decades of combined expertise and an independent perspective on a diverse range of aircraft and engine makes and models; including Beechcraft, Bombardier, Cessna, Embraer, Falcon, Gulfstream, GE, Honeywell, Pratt & Whitney Canada, Rolls-Royce, and many more OEMs.

All JSSI appraisers carry the highest accreditation from the ASA. In fact, we have one of the largest teams of ASA-accredited appraisers on staff in the industry. We bring decades of technical experience and maintenance data to every appraisal to ensure an accurate valuation for your aircraft using resources unavailable to the rest of the market. While all ASA appraisers provide accuracy and follow common practices, only our appraisers have the full resources of JSSI behind them.

With personal consultation and extensive communications throughout the process, you’ll receive unrivaled customer service and an in-depth review of the completed appraisal. We are uniquely positioned to leverage a unique combination of MRO relationships, technical expertise and market knowledge to provide an accurate appraisal tailored to your aircraft.

We are the experts in aircraft ownership and operating costs. Over 2,000 business jets, regional jets and helicopters are on JSSI programs across the globe. We support more than 200 airframes, 700 APUs, 4,000 engines, and 10,000 maintenance events each year across multiple makes and models.
