Riveted joints remain common in metal airframes because they

  • A.Introduce no stress concentration
  • B.Require no surface preparation
  • C.They are inspectable and repairable
  • D.Are lighter than any bonded joint

Answer: C

A rivet line can be examined, individual fasteners replaced and its fatigue behaviour predicted from a large body of data. Bonded joints can be lighter and avoid the holes, but they are harder to inspect and to repair, which is why fasteners persist even alongside adhesives.
