(DHS is the CAA recognised Type Design Organisation for almost all the de Havilland piston aircraft.  A comprehensive service of design and engineering support is available, backed up  by the extensive drawings, calculations and notes surviving in the B.Ae archives, now transferred to DHS.  Please note that by agreement with B.Ae, drawings are not available for the construction of replica aircraft, but are available at a fee for the restoration, repair and maintenance of genuine DH products.  Full details of the services and spares available from DHS can be found on the website)

These plans are currently being used to support projects in Switzerland and Sweden, are dimensioned in metric and annotated in English and German.  It is stressed that these plans are not DH plans and are offered in good faith but without supporting calculations or warranties, for the convenience of home designer/builders only)
