What items must be entered into the aircraft records after maintenance is performed?

The correct response highlights the essential components that must be documented in the aircraft records following maintenance work. The description of the work performed is vital as it provides a clear account of what maintenance was conducted, which is crucial for future reference and to maintain the aircraft’s airworthiness. Including the date completed is necessary for tracking the maintenance history and ensuring compliance with maintenance schedules.

The signature of the mechanic conveys accountability and professionalism, confirming that the work was performed by a qualified individual who adheres to regulatory standards. This documentation is critical not only for regulatory compliance but also for maintaining a thorough maintenance history, which is vital for the ongoing safety and airworthiness of the aircraft.

While other options include some relevant information, they lack the comprehensive elements required in maintenance records. Thus, the option that includes the description of the work, the completion date, and the mechanic’s signature best aligns with FAA regulations and industry standards for proper record-keeping.
