Airport Authorities may now submit their airport revisions - Aeronautical Chart Changes,
(ACCs )& Aeronautical Data Changes, (ADCs), directly to NFDC.
The web portal can be found at https://nfdc.faa.gov/xwiki/bin/view/NFDC/WebHome.
In this case, you can submit an Aeronautical Chart Change with supporting Documentation such as an Airport Layout Plan at https://nfdc.faa.gov/xwiki/bin/view/NFDC/ACC.
These changes will be applied to the Airport Diagram, and sketches in both the AFD and Instrument Approach Plates.
