14 CFR 417

Not found in the current CFR. No part 417 exists under title 14 in the eCFR as of 2026-08-23. That means either the part was removed or renumbered, or the citation in the publication is wrong. Either way, verify before relying on it — this is exactly the kind of stale reference worth catching.

What happened to it — verified: This was Launch Safety (FAA commercial space launch licensing). Consolidated out of existence by the FAA's Streamlined Launch and Reentry License Requirements rule: part 450 replaced parts 415, 417, 431 and 435 (transition completed 2021 - 2026). What to look to now: 14 CFR 450, Launch and Reentry License Requirements. [source]

Citation counts come from the publication text, not from a summary. A high count is frequency, not legal weight — open the pub and read the citation in context.
