Which of the following is included in the criteria for USCG weight and balance computations?

• A. At initial delivery
• B. During programmed depot maintenance
• C. When major modifications or repairs affect weight and balance
• D. All of the above

Answer: (D)

Weight and balance calculations must be updated any time the aircraft’s weight distribution could change, so the flight envelope and performance remain within safe limits. At initial delivery you establish the baseline for all future checks. During programmed depot maintenance, parts may be added or removed and configurations can change, which can shift weight or the center of gravity. If a major modification or repair affects weight or how mass is distributed, a fresh calculation is necessary to verify the aircraft remains within allowable limits. Because each of these situations can alter stability, controllability, or structural margins, all of the listed scenarios are included in the criteria for weight and balance computations.
