A330/A340

 

Strand have extensively worked on the A330-200F General Market Freighter. The analysis that were carried out are; F&DT checkstress (certification) of the aileron, spoiler and flap support structure. The F&DT capability of the ribs and skin-centre spar were also evaluated at checkstress. A fatigue stress survey was performed to identify locations that were susceptible to fatigue damage. Typical features considered include lugs, bolted joints, manholes and castellations. A full fatigue calculation was performed for these locations and based on the fatigue life, a damage tolerance site selection was performed. Full damage tolerance calculations were performed for these locations and the inspection threshold and intervals derived.
