Abstract
A tripod jack collapsed when hoisting an aircraft being overhauled. The load capacity of the jack was 30 ton, and the cause of failure was corrosion in the weld region of a leg extension. During breakdown, a spacer in the tripod jack assembly also failed as the result of secondary damage. The failed spacer joins six braces in the assembly of jack. Material of the spacer was mild steel (AISI 1005). Failure of the leg extension imparted an imbalance on the underload structure of the jack. The spacer initially deformed and fractured partly by dimpled rupture and finally failed in a brittle, transgranular manner due to change in loading condition as the jack collapsed catastrophically.
