What identifies a safety supplement within technical orders?

A safety supplement within technical orders is specifically designated by a red border along with the letters "SS." This red border is a clear visual cue that signifies the presence of important safety information that requires attention from personnel. The use of "SS" stands for "Safety Supplement" and highlights that the information contained within that section is critical for ensuring safe operations and practices related to the technical orders.

This format allows readers to quickly identify sections that contain crucial safety advisories or changes, ensuring that they are not overlooked. Understanding this identification method is vital for aircrew and maintenance personnel to ensure compliance and to prioritize safety in their operations.
