A Plane without AS9120 Certified Parts Might Crash with its Maker

For safety’s sake Quality management standards need to be stringent, especially for the aerospace industry because lives and substantial investments are on the line. With so much at stake, plane manufacturers need to go the extra mile to find certification bodies like International Standards Authority, Inc. to conduct an external audit for them after an internal team does one initially. Auditors check for adherence to standards set by the aerospace industry, ensures the parts are traceable, and certifies that the manufacturing processes are sound and reliable. In the event of negative findings, auditors will have to be made aware of how those findings will be corrected or addressed. Only then will genuine AS9120 certification be issued.
