Landing gear steel pin

Failure of a Landing Gear Steel Pin A landing gear pin failure occurred in the cylindrical part of the pin whose outer surface was corroded (Sastri et al. (19), p. 515, Fig. 7.78). The fracture surface with convergent chevron patterns at the initiation site and a cover of corrosion product on the surface is shown in Sastri et al. (19, p. 516, Fig. 7.80). Corrosion pits were present at the exterior surface of the cylindrical pin. Pitting corrosion was also present at the fracture initiation site.
