Part 117 describes flight and duty limitations and rest requirements for flight crew operating under which regulation?

• A. Flight crew rest requirements for Part 91 operations only
• B. Flight and duty limitations and rest requirements under Part 117
• C. Aircraft certification requirements
• D. Airworthiness standards for imported aircraft

Answer: (B)

Flight time limits, duty periods, and rest requirements are governed by Part 117. This regulation sets the rules for how long a flight crew may fly in a day or month, how long a duty period can last, and the minimum rest between duties to manage fatigue. It applies to operations that are conducted under the Part 117 framework (and the associated air carrier operations under Parts 121, 125, or 135), providing the standardized hours-of-service rules for those crews. The other topics listed—aircraft certification and general airworthiness standards—are handled in different parts of the regulations, and Part 91 operations follow different, less prescriptive rules. So the description of flight and duty limitations and rest requirements belongs to Part 117.
