What key information must be included in maintenance records under FAR Part 91 inspections?

In maintenance records under FAR Part 91 inspections, it is essential to document the inspection date and the aircraft's total time. This information serves as a critical record for tracking the maintenance history of the aircraft, ensuring compliance with regulatory requirements, and helping to establish a reliable maintenance schedule.

The inspection date is crucial as it indicates when the maintenance was performed and helps identify whether the aircraft is within the required inspection intervals. The total time, usually noted in flight hours or cycles, reflects the wear and usage of the aircraft, which provides valuable context for assessing maintenance needs and compliance with airworthiness directives.

Other information, such as reference technical data, FAA Form 337, and details about the aircraft make, model, and serial number are also important but are typically used in different contexts in maintenance records. While they contribute to a complete picture of the aircraft's maintenance status, they do not encompass the fundamental tracking of when inspections occur and how much the aircraft has been utilized, which is why the combination of the inspection date and total time is particularly emphasized.
