What is a SB?

Explanation:
A Service Bulletin is the manufacturer’s recommended modification or improvement to an aircraft, system, or component. It outlines what to change, why the change is beneficial, and how to perform it, often including required steps, parts, and procedures. This is not something mandated by the FAA by default; it becomes mandatory only if an authority directive (like an Airworthiness Directive) requires it or if the operator chooses to implement it under policy or maintenance planning. It’s not simply a cosmetic update, and while some SBs may involve software changes, the primary purpose is to document a recommended modification from the manufacturer, not a fixed software patch.
