What document lists the leveling means used for an aircraft?

• A. Type Certificate Data Sheets for the aircraft.
• B. Maintenance Manual.
• C. Flight Manual.
• D. Airworthiness Directive.

Answer: (A)

Leveling an aircraft for maintenance and weight-and-balance work is governed by the official design documentation for that aircraft type. The Type Certificate Data Sheet is the source that documents the approved type design, including the specific leveling means or devices that must be used to level the aircraft on the ground. This ensures a consistent, correct attitude during inspections and measurements, based on what the manufacturer has approved.

Other documents serve different purposes: the Maintenance Manual provides procedures for maintenance tasks, the Flight Manual covers operating procedures, and Airworthiness Directives dictate mandatory safety actions. None of those establish the official leveling means for the aircraft, so the correct source for that information is the Type Certificate Data Sheet.
