What is the primary purpose of FAA Part 139 certification for airports that serve scheduled passenger service?

• A. It regulates air traffic control services.
• B. It sets minimum safety standards for airfield operations and ongoing compliance to operate such airports.
• C. It defines aircraft noise abatement procedures.
• D. It establishes pricing for landing fees.

Answer: (B)

The main idea being tested is that Part 139 focuses on safety standards and ongoing compliance for airports that handle scheduled passenger service. Part 139 requires certificated airports to meet minimum safety requirements for airfield operations—covering areas like runway and taxiway maintenance, inspections, wildlife management, emergency planning, firefighting/rescue capabilities, and security—and to stay in compliance through FAA inspections and an approved certification manual. This framework ensures consistent, safe operations at airports with regular passenger traffic. The other options don’t fit because Part 139 does not regulate air traffic control services, define aircraft noise abatement procedures, or set landing fee pricing.
