Failure occurred in a type 304 stainless steel leaf spring attached to the undercarriage assembly of an airport shuttle train. Failure analysis showed that the fracture was caused by low-cycle, reversed bending fatigue. The stresses leading to failure were imposed by poor alignment. It was recommended that improved assembly procedures be used and that, if another failure occurred, a steel of higher fatigue strength be used.
