The (AIA/NAS NAS0331) standard is a critical aerospace technical specification titled "Bearing Installation and Retention by Swaging or Staking" . It provides the industry-wide requirements for securing bearings—particularly spherical and plain bearings with grooved outer races—into structural housings like landing gear, flight controls, and engine mounts.

: Represents the maximum grip length (the thickness of the materials being joined). cross-reference to a commercial equivalent like CherryMAX or Huck rivets? nas0331 pdf
