STATISTICAL CONTROL OF QUALITY Available to Purchase

WE presume that everyone concerned with production in the aircraft industry or one of its ancillaries—whether as an aeroplane constructor, sub‐contractor or maker of parts or auxiliary equipment—is by now familiar with what has come to be known, colloquially, as “Quality control.” We publish in this issue, by courtesy of the SOCIETY OF AUTOMOTIVE ENGINEERS, a paper read last autumn during the Society's National Aircraft Production Meeting by MR. J. W. DUNN, whose duty it is to direct and co‐ordinate quality control and inspection policies of the whole of the Curtiss‐Wright group of companies.
