A detailed document providing instructions for the upkeep and repair of specific parts of equipment or systems. These manuals typically contain procedures for inspection, testing, disassembly, repair, reassembly, and troubleshooting. For example, an aircraft part manufacturer will produce this type of manual to guide technicians in maintaining the landing gear components they manufacture.
These documents are essential for ensuring operational reliability and safety. Adherence to the outlined procedures helps to extend the lifespan of parts, minimize downtime, and prevent accidents resulting from faulty maintenance practices. Historically, these manuals were primarily paper-based, but the increasing complexity of modern systems has led to a shift towards digital formats that offer greater accessibility and ease of updating.
