US Air Tool Company (also known as USATCO) has been a family owned and operated business since 1951. USATCO's founder, Joseph Percz, began the company in the basement of his home repairing surplus aircraft tooling. We are now a US manufacturer and worldwide distributor of high quality tools for the aviation industry with offices in New York California. In addition, from the beginning of the homebuilder era in the 1970's, USATCO has been providing tools and equipment to craftsmen around the world who build and fly their own aircraft. These "sheet-metal artists" are now flying thousands of planes built and maintained with USATCO tools.
