What information does a maintenance manual provide for aircraft technicians?

The correct answer highlights the primary purpose of a maintenance manual, which is to provide aircraft technicians with detailed procedures for the maintenance and troubleshooting of aircraft systems. These manuals serve as comprehensive resources that outline step-by-step instructions, specifications, and best practices necessary for the proper upkeep of various aircraft components and systems. By following these procedures, technicians can ensure that the aircraft operates safely and efficiently, addressing any mechanical issues that may arise during operation.

In contrast, while flight safety regulations are essential for overall aviation safety and compliance, they do not typically form the main content of a maintenance manual. Similarly, details of mandatory training programs pertain more to the qualifications and training requirements for technicians rather than the direct maintenance processes. Guidelines for passenger service operations are related to customer-facing services and are not relevant to the technical maintenance and troubleshooting role that the maintenance manual addresses.
