Since their winglet technology certification, Tamarack has been working to sell the product to business jets and commercial airlines; they also offer additional engineering services to regional businesses. Klinginsmith said their facility has over 17,000 square feet across three buildings. They have an administrative building, a production and installation hangar, and an R & D facility where their engineers take on additional engineering services work in the aerospace industry.
Cropper said both he and Klinginsmith attended the University of Idaho, along with several others in the organization. Cropper also serves as an FAA Designated Engineering Representative( DER) at Tamarack ' s location. He manages 10 engineers and designers for both internal development of the winglet program and external engineering projects. He said they do everything, from testing and certification to flight testing.“ We are a group of engineers that like to solve problems and get our hands dirty."
For external customers, Tamarack offers " small box development, like hardware design, such as an

electrical or mechanical component, to designing a clean sheet aircraft, including aerodynamic loads." They have also undertaken helicopter projects and integrated complex hardware into airframes. They can define requirements for system architecture for Part 23, 25, or 27.
He complimented his team by sharing how well they identify the customer ' s critical needs holistically, going so far as to review detailed designs within the airframes while rapidly reporting recommendations. " We have a whole bunch of generalists, and we also have a few people who are experts in certain areas. We have a broad knowledge base to solve problems for people," Cropper shared.
Cropper noted that one of their longterm client relationships for external engineering services involved a start-up with an integration project aimed at enabling them to meet certifications. " The relationship has grown as the company has matured; they ' ve added people to their team, but they only have a couple of people focused on aerospace." He said that, as engineering experts, they augment their customers ' team. " Relationship-
