What publication is issued by airframe, engine, and component manufacturers to notify aircraft owners of design defects?

Service Bulletins are key publications issued by manufacturers, including those of airframes, engines, and components, to inform aircraft owners and maintenance personnel about design defects, necessary repairs, or modifications required to ensure continued airworthiness. These documents provide essential details on potential issues that could affect safety and performance, often outlining steps for correction and compliance.

The intent is to notify operators proactively, allowing them to make educated decisions regarding maintenance and safety measures. Service Bulletins can include instructions on inspections, parts replacements, or alterations that need to be made to rectify any identified problems or enhance the aircraft's reliability.

Understanding the role of Service Bulletins is crucial for those involved in aircraft maintenance and operations, as they help ensure that any design flaws are addressed promptly, thus maintaining operational safety for all involved. The other publications listed serve different purposes: Technical Orders generally relate to military specifications, the Aeronautical Information Manual provides a broad overview of aviation regulations and operating information, and the Aircraft Maintenance Manual is focused on providing maintenance guidance specific to a particular aircraft type but does not typically serve as a vehicle for notifying design defects.
