Construction and Fuselage
The structure of the fuselage is a conventional alloy construction (non-pressurized fuselage).
The structure of the wing is new technology. While a conventional wing has a main and a secondary spar, ribs and stringers and sheet metal skin – rivited together – the Dornier 228 wing structure is a box formed from four integrally milled alloy panels. Leading edge is conventional alloy sheet metal with ribs and stringers, trailing edge and fowler flaps are made from Cevlar.
