What benefit does AC 107-2A describe for maintaining maintenance and inspection records on a small UAS?

Why: AC 107-2A describes recordkeeping as a voluntary best practice with safety value: "Maintenance and inspection recordkeeping provides retrievable evidence of vital safety assessment data defining the condition of safety-critical systems and components supporting the decision to launch." It helps establish a reliable maintenance schedule and track component service life over time.

• AC 107-2A frames recordkeeping as a beneficial practice owners and operators "may find" useful, not an FAA-mandated submission required before every flight.
• Recordkeeping documents past maintenance history; it does not substitute for the preflight inspection § 107.49 requires before each individual flight.
