Required Service Center Equipment

The implementation of the accreditation program requires key pieces of equipment such as a temperature-controlled, water mist burn off oven, and a test panel. However, since many EASA members and other program candidate service centers have already invested in this important equipment, additional outlays to bring equipment into conformity are expected to be minimal. Unless noted otherwise, all equipment listed must be on site, functional and calibrated at least annually to applicable national standards. (Note: Outsourcing of some but not all repair activities is permitted, but the outsource vendor must provide documentation to confirm that repairs meet the requirements of this program. If outsourced repair requires measurements or testing, proof that calibrated equipment was used is also required.)

  • Unless otherwise noted, all equipment listed must be on site and functional.
  • Except for gauge blocks, all instruments must be calibrated at least annually to applicable national standards.
  • Service center is to have a documented list of all calibrated equipment including unique identification of each item and retain at least a 3-year record of previous calibrations.
  • Verification: Confirming, through the use of objective evidence, that specified requirements have been fulfilled.
