Definition
Resilient pads or bushings, typically made of rubber bonded to metal, used to attach an aircraft engine, instrument panel, or other vibration-sensitive component to the airframe. Shock mounts absorb engine vibration and minor impact loads while still holding the component firmly in place.
Plain English
Rubber-and-metal cushions that bolt an engine or instrument panel to the airframe so vibration and bumps don't get passed straight into the structure.
Context Anchor
Seen during aircraft maintenance and inspections where instruments, radios, panels, or other equipment are attached to the aircraft structure.
Derivation
From 'shock' (a sudden jolt or vibration) and 'mount' (a fitting that holds something in place). The name describes the job exactly: a mount that absorbs shock.
Why Pilots Care
They reduce vibration transmission, protecting components from fatigue, improving instrument readability, and enhancing passenger comfort.
Analogy
Shock mounts work like the rubber feet under a machine: they do not stop all movement, but they reduce how much shaking reaches the item being protected.
Intuition Check
Shock mounts are not electrical parts and they do not create shock. They are supports that absorb or reduce sudden force and vibration.
Example Sentence 1
During the preflight inspection, the technician noticed the engine was sitting low on one side and traced it to a collapsed shock mount.
Example Sentence 2
Worn shock mounts allowed vibrations to reach the cockpit instruments during flight.
