Where Aerospace Shims Are Used

Shims are specified across aircraft and spacecraft systems to maintain alignment, control spacing and reduce vibration in assembled components. Common aerospace applications include:

  • Airframe Assembly and Alignment: Shimming fuselage, wing and tail section joints to achieve structural accuracy and meet assembly tolerances during new-build and repair.
  • Engine Component Spacing: Setting correct clearances between compressor stages, turbine sections and auxiliary engine components.
  • Landing Gear Maintenance: Adjusting geometry, load paths and bearing clearances in undercarriage components during scheduled overhauls and unscheduled repairs.
  • Cockpit and Cabin Fit-Out: Achieving precise alignment of instrument panels, seating rails, consoles and avionics mounting points.
  • MRO (Maintenance, Repair and Overhaul): Fitting or replacing shims during structural inspections, component upgrades and scheduled maintenance intervals.
