Which statement about private aircraft weighing requirements is true?

• A. Private aircraft are required by regulations to be weighed periodically.
• B. Private aircraft are required to be weighed after making any alteration.
• C. Both statements are true.
• D. Neither statement is true.

Answer: (D)

The essential idea here is how weight and balance data are managed, not a routine weighing schedule. For private aircraft, there isn’t a universal requirement to weigh the airplane on a set periodic basis. Likewise, you don’t automatically have to reweigh after every alteration. What matters is that the weight and balance data reflect the current configuration of the aircraft and are available for flight planning and compliance. If a modification changes weight or the center of gravity, you update the data—often by recalculating from the known weights of the new components or, if necessary, by reweighing—to ensure the aircraft remains within allowable limits. Because there’s no blanket rule demanding periodic weighing or weighing after any alteration, both of those statements are not true.
