Fuel quantities at touchdown shall be reported to maintenance if combined Aux Tank Fuel quantities exceed _______.

• A. 1000 lbs
• B. 1500 lbs
• C. 2000 lbs
• D. 2500 lbs

Answer: (C)

The main idea is how much fuel in the auxiliary tanks at the moment of touchdown can affect the aircraft’s weight and balance and trigger maintenance accountability. When the combined quantity in both auxiliary tanks is two thousand pounds or more, it warrants notifying maintenance. This threshold ensures that the fuel load is recorded, gauges are verified for accuracy, and the fuel system is checked for leaks or anomalies before the next flight. At that level, the extra weight can meaningfully influence landing performance, CG considerations, and post-flight maintenance actions, so keeping maintenance informed helps maintain safe and accurate weight/balance data for subsequent missions. Lower amounts do not cross that threshold, so the formal maintenance notification isn’t required.
