Aircraft Certification Product Issues Lists
The Aircraft Certification Service's Policy and Standards Division (AIR-600) maintains product issues lists that identify all known certification related issues for specific product types. These lists ensure that certification issues are identified upfront for all certification projects. These lists should not be considered comprehensive, since new issues commonly arise. AIR-600 keeps the lists up to date and makes them available to the public as appropriate.
