What is the role of a maintenance log?

The role of a maintenance log is to document all maintenance actions and inspections performed on the aircraft. This is crucial for ensuring the aircraft's safety, reliability, and performance. Each entry provides a detailed account of repairs, findings from inspections, parts replaced, and any discrepancies observed, which helps maintain a thorough history of the aircraft's maintenance. This information is vital for oversight by regulatory bodies, ensuring compliance with safety standards, and supporting future maintenance decisions.

While tracking fuel consumption, flight hours, and modifications are important for various aspects of aircraft operation and management, they do not encompass the comprehensive and critical nature of a maintenance log, which focuses specifically on the upkeep and serviceability of the aircraft through recorded maintenance actions.
