What does the TESTED acronym stand for in locating structural components on aircraft?

• A. Tips, Engine, Surfaces, Tail, Ext devices, Doors
• B. Tips, Engine, Surfaces, Nose, Ext devices, Doors
• C. Tips, Engine, Hull, Tail, Ext devices, Doors
• D. Tips, Engine, Surfaces, Tail, Ext devices, Doors

Answer: (A)

TESTED is a mnemonic used to locate key structural components on an aircraft during investigations. The letters map to: Tips, Engine, Surfaces, Tail, Exterior devices, Doors. This arrangement guides you to check the parts where loads and attachments are most critical: the wing tips, around the engine and its mounting, the major surface areas of the airframe, the tail section, external devices like antennas, and the access doors. The other options deviate by substituting terms like Nose or Hull, which aren’t part of this established grouping, so they don’t align with how the TESTED mnemonic organizes structural locations.
