Definition
A United States federal agency established in 1934 within the Department of Commerce, responsible for regulating civil aviation in the U.S. It replaced the Aeronautics Branch and was tasked with promoting air commerce, certifying pilots and aircraft, establishing airways, and improving air navigation infrastructure. It existed until 1938, when its functions were transferred to the newly created Civil Aeronautics Authority.
Plain English
A government office that ran U.S. civil aviation between 1934 and 1938. It set the rules for pilots, aircraft, and airways before today's FAA existed.
Context Anchor
Seen in FAA history material when explaining how U.S. civil aviation oversight developed before the FAA.
Derivation
"Bureau" comes from French, meaning a government office or department. "Air Commerce" reflects the agency's mission: overseeing the business and operation of flying. The name signals that early aviation was treated as a form of commerce needing federal oversight, much like shipping or rail.
Why Pilots Care
Knowing this agency helps pilots understand how today's FAA evolved. Many of the basic regulatory ideas pilots still operate under -- pilot certification, aircraft airworthiness, and published airways -- trace back to the Bureau of Air Commerce era.
Intuition Check
Do not read this as a current FAA office. The Bureau of Air Commerce was a historical predecessor to later federal aviation agencies, not the modern FAA itself.

Example Sentence 2
