Mitsubishi Aircraft has introduced a stretched variant to its MRJ regional jet family and unveiled extensive design changes, including using aluminium instead of carbonfibre composites for the aircraft's wings.
With the aluminium wings, the company moves away from its earlier aim of using significant amounts of composite materials for the airframe. The result is that the only remaining composite parts will be the empennage, horizontal tail and vertical tail, amounting to 10-15% of the total airframe
