ENGINEERING LIAISON and PRODUCTION CONTROL

MANY of the differences between engineering and production units arise from the fact that the former are too far from the product which they have conceived to appreciate its deficiencies, and the latter are not qualified by experience to improve upon it. As a result, changes intended to correct a defect have bred others which, in turn, have necessitated additional modifications.

By the assignment of a third group, an engineering liaison, which is familiar with design requirements to observe the assembly and test, and other production phases of aircraft engines, the correction of basic faults and the elimination of unnecessary changes in design or procedures, have been possible. Examples of typical troubles and other methods of correction are cited in this paper.
