When are adverse loading checks conducted?

Adverse loading checks are specifically conducted anytime a repair or alteration results in the empty center of gravity (CG) moving outside the established limits. This is critical for maintaining the aircraft’s stability and safety, as any shift in the CG can significantly affect handling characteristics and performance. If the CG is not within the specified range, it could lead to difficulties in controlling the aircraft and could pose safety risks during flight.

While other situations, such as maintenance or changes in fuel levels, might indirectly affect weight and balance, they do not specifically trigger the need for an adverse loading check in the same direct manner as alterations that impact the CG. Thus, the correct scenario for conducting these checks is solely focused on alterations affecting the empty CG range.
