Why is it essential to refer to the aircraft maintenance manual during assembly?

Referring to the aircraft maintenance manual during assembly is crucial because it contains specific procedures and specifications that have been established by the manufacturer. These guidelines ensure that the assembly process is performed correctly and safely, adhering to the standards required for the aircraft's operation. The manual provides details such as torque specifications, assembly sequences, and the types of fasteners to use, all of which are critical for maintaining the structural integrity and performance of the aircraft.

Following these manufacturer-defined procedures not only enhances safety but also ensures compliance with regulatory requirements, as deviations could lead to serious operational issues or even accidents. The manual serves as the authoritative source of information that technicians and engineers rely on to maintain consistency, reliability, and safety throughout the assembly process. This makes adhering to the manual an essential practice in aircraft maintenance and assembly.
