Final answer:
Mechanics can find airworthiness standards for transport category aircraft in the Federal Aviation Regulations (FARs), specifically in Part 25, which includes certification requirements necessary for the aircraft's safe operation.
Step-by-step explanation:
A mechanic looking for the airworthiness standards for transport category aircraft can find this information in a specific part of the aviation regulations known as the Federal Aviation Regulations (FARs), specifically in Part 25. These regulations outline the standards required for aircraft to be considered safe for flight. They cover various aspects of the aircraft including structure, design, features, and performance requirements.
FAR Part 25 contains comprehensive information that addresses the certification requirements of transport category airplanes. This section is crucial for mechanics and engineers who are responsible for ensuring that the aircraft meets all the necessary conditions for safe operation before it is deemed airworthy.
