Companies that participate in the ASA-100 Accreditation Program. Most certificates are for 3 years. For a company to be accredited to ASA-100, the company is audited by an ASA approved ASA-100 auditor to the requirements of ASA-100 and AC 00-56. The ASA-100 certificate includes a statement of compliance to FAA AC 00-56. A company being listed on the ASA-100 list should not be the only factor evaluated when approving a company for a business transaction as there may be legal requirements that must be checked and other business factors that should be evaluated.
