Quality Program

 

Our commitment to quality is exemplified by our registration to AS9100 since 2007. In addition, we have been audited and approved by GE Aviation, UTC, Boeing, and NASA Marshall Space Flight Center for flight with no restrictions (Supplier # 80), and these have led to a number of approvals by prime and sub-contractors and inclusion in Ship-to-Stock programs. Our QC room is temperature controlled to 70 +/-2 degrees F. Our Calibration complies with the ANSI /NSL Z540-1 standard. Inspections are performed with tolerances ranging to .0001″.
