AS9100C Differences

AS9100C Transition Plan

The International Aerospace Quality Group (IAQG) has proposed a 30-month transition timeline for existing certified organizations. However, due to the need for global harmonization and the release of supporting standards, the start date for transition had not been set (as of the date of this article).

A possible scenario could be:

January 2009: 
AS9100C was released.

March 2009 – August 2009 
(6 months for training providers to develop training for the new standard)

September 2009 – August 2010: 
(12 months to train certification bodies and auditors)

September 2010 – August 2011: 
(12 months for all companies to update to the new standard at their next surveillance or recertification)

The On-line Aerospace Supplier Information System (OASIS) database will be used to share IAQG expectations and track client transition activity via certification body issuance of AS9100C certificates. The AS9100C transition start date will be communicated via OASIS when it becomes available.

In regard to auditor training, the IAQG Other Party Management Team (OPMT) is developing sanctioned training for aerospace auditors. All Aerospace Auditors (AA, AEA, and AIEA) will be required to complete this supplemental training prior to conducting any AS9100C audits for certification purposes under the Industry Controlled Other Party (ICOP) process. This training will cover transition and client assessment to the AS9100 series of standards (9100, 9101, 9110, and 9120).

The Aerospace standard, AS9100:2009, Revision C, is available for purchase at the SAE web site ( for a member price of $48.00, or list price of $61.00. The standard can be ordered at the ASQ web site ( for a member and list price of $61.00.

AS9100C Differences

The differences in AS9100C versus AS9100B are described in my paper, Changes in AS9100C, that can be downloaded as a PDF file from our web site.

Additions based on the changes from ISO 9001:2008 are underlined and highlighted in the paper as yellow. Additions in the unique AS9100C parts of the text are underlined and highlighted in green. All the unique unchanged AS9100C text is shown in bold.

The underlining of new text will allow readers to spot the additions, even if the paper is printed without color. AS9100C and ISO 9001:2008 texts are shown inside boxes and in Italics to help separate the text from the comments. Deleted text from ISO 9001:2000 and AS9100B is indicated by strikethroughs.

Most of the text in AS9100B (and ISO 9001:2000) was not affected by AS9100C (and ISO 9001:2008). The unaffected parts of AS9100B, carried over unchanged into AS9100C, are not repeated in the paper.
