Where is the entry recorded after completing a 100-hour inspection?

The entry after completing a 100-hour inspection is recorded in each separate maintenance record for the airframe, powerplant, and propeller. This is crucial because regulatory requirements dictate that all maintenance performed on components of an aircraft must be documented accurately in their respective records.

Each type of record serves a specific purpose for tracking maintenance history and ensuring compliance with airworthiness standards. The airframe maintenance record specifically captures any work done related to the airframe, while the powerplant and propeller records provide similar detail for those respective components. Maintaining these records helps ensure that the aircraft is properly maintained and allows maintenance personnel and regulatory authorities to review the maintenance history easily.

The other options do not provide a full compliance with the regulatory requirements or proper documentation practices. Central maintenance logs may summarize maintenance but do not provide the necessary individual records for each component. Recording only in the airframe maintenance record neglects the powerplant and propeller, while entries in a pilot's personal logbook are meant for pilot experience and qualifications, not for aircraft maintenance records. Therefore, the most comprehensive and compliant choice is to record in each separate maintenance record.
