June 30, 2015 - After selling Fullerton Air Parts, Bob and Flo Irwin formed a new company called Aircraft Spruce Company (Aircraft Spruce) in 1965. The company initially started off selling one product, and that product was aircraft grade lumber that was made from the spruce tree. The lumber was used for aircraft construction and restoration.

As the company grew, Bob and Flo began to take on new products to sell to their customers. As Bob began to take on new products he began to assemble a catalog. At which time the company changed its name to Aircraft Spruce & Specialty Co. The company catalog has grown to over 900 pages and over 80,000 products and employs over 150 employees.
