Definition
A hinged linkage, also called a torque link or torque arm assembly, that connects the upper and lower portions of a landing gear shock strut. It allows the strut to compress and extend along its axis while preventing the lower portion from rotating relative to the upper portion, keeping the wheel aligned with the direction of travel.
Plain English
A two-part metal link, hinged in the middle like a pair of scissors, that joins the top and bottom of a shock strut. It lets the strut squeeze up and down on landing but stops the wheel from spinning sideways.
Context Anchor
Seen during landing gear inspection or preflight, especially around the nose gear or main gear shock strut.
Derivation
Named for its shape and motion. The two arms are pinned together in the middle and open and close like household scissors as the strut compresses and extends.
Why Pilots Care
If a scissors link is loose, cracked, or disconnected, the wheel can rotate freely on the strut, causing severe shimmy, loss of steering, or directional control problems on the runway.
Intuition Check
Scissors here does not mean a cutting tool. It means a crossed, hinged landing-gear linkage that keeps the wheel aligned.
Example Sentence 1
During preflight, the pilot checked the nose gear scissors for security and signs of wear at the center pivot bolt.
Example Sentence 2
As the gear retracted, the scissors folded to allow the strut to tuck fully into the wheel well.
