Part 135 operations have MTOW limit of

• A. 8618 kg or less
• B. 8618 kg or more
• C. 10000 kg or less
• D. 5000 kg or less

Answer: (A)

Part 135 rules are built around operating smaller, on‑demand aircraft, and the weight threshold used to classify these operations is the aircraft’s maximum takeoff weight. The limit is 8,618 kilograms or less, which is about 19,000 pounds. Keeping an aircraft at or below this weight places it in the smaller‑aircraft category for Part 135, with implications for certification, crew requirements, maintenance programs, and operating limitations. Heavier aircraft generally fall under different parts with stricter requirements, so this weight boundary distinguishes which set of rules applies.
