Approved Flight Manual Supplements supersede which of the following?

Approved Flight Manual Supplements (AFMS) are critical documents that provide aircraft operators with updated information necessary for the safe operation of their aircraft. When a supplement is approved, it can alter or add to the information found in the original manufacturer's manuals.

The reason the original manufacturer's manuals are superseded is that the AFMS incorporate updated information that is based on operational feedback, safety assessments, or changes in procedures and equipment that may not have been available at the time the original manual was written. This ensures that pilots and maintenance personnel are operating based on the most current data available, which is vital for maintaining safety and compliance with regulations.

In contrast, regulations set by the FAA, the aircraft's weight and balance guidelines, and maintenance repair bulletins have different roles and methodologies associated with them, thus they are not directly superseded by the AFMS. Regulations set by the FAA provide the legal framework for operation, weight and balance guidelines are specific operational parameters crucial for safety, and maintenance repair bulletins deliver specific maintenance information independent of the operational guidance provided by the AFMS.
