Clients who are already certified to AS/EN 9100 series or ISO 9001 are already well on their way to meeting the requirements of AC 00-56B and it may be possible to combine audit cycles for these schemes.
AC 00-56B - voluntary industry distributor accreditation program is a voluntary program for civil aircraft parts distributors which is owned and strongly endorsed by the US Federal Aviation Administration (FAA) to establish eligibility of parts and products. Whilst the scheme is owned by the FAA, it is recognized by the industry in other areas of the globe, and sometimes flowed down as a customer requirement.
BSI offers a scheme to enable clients to be assessed against AC 00-56B and to receive a declaration document to demonstrate compliance with the requirements of the program. BSI documents are recognised by the FAA, and are valid to list your organization on the official Aviation Suppliers Association register.
