It's Our Culture. AS9100D / ISO 9001:2015 Certified — World Class Supplier status, earned, audited, and renewed every single day at our Deer Park, NY facility. Our Philosophy ## World Class Is a Discipline, Not a Slogan. In the build-to-order aerospace market, TEK Precision is among a very select group of premier suppliers recognized by OEMs as a World Class Supplier of flight safety-critical hardware (https://tekprecision.com/products) and services. This reputation was not earned through rhetoric — it was built through a relentless and continuous pursuit of process quality improvements integrated throughout every segment of our business — and reflected in two decades of Sikorsky, Northrop Grumman and UTC supplier awards (https://tekprecision.com/awards).
