This IPC category does not have the same number in the CPC system. I don't know the reason.
But a note here: https://www.uspto.gov/web/patents/classification/cpc/html/cpc-B.html#B64C says that Items in IPC B64C35/02 are now "covered by" CPC B64C35/00, which is a patent classification for Seaplanes and flying boats.
