What type of document is typically found in the flight deck regarding aircraft history?

The document that is typically found in the flight deck regarding aircraft history is the Air Maintenance Log. This log is crucial because it contains detailed records of all maintenance activities performed on the aircraft, including inspections, repairs, and modifications. These records help ensure that the aircraft is in compliance with safety regulations and is airworthy.

Maintaining an accurate Air Maintenance Log is vital for tracking the maintenance schedule, assessing the overall health of the aircraft, and verifying compliance with regulatory requirements. It also serves as a legal record in the event of an investigation regarding aircraft performance or safety incidents.

While other documents like the Airline Certificate, Air Cargo Manifest, and Passenger Manifest serve important roles, they do not specifically document the aircraft's maintenance history. The Airline Certificate indicates the airline's authorization to operate, the Air Cargo Manifest details the cargo being transported, and the Passenger Manifest lists the boarding passengers—all of which, while critical for operations, do not provide the historical maintenance records needed for safety oversight.
