Drawing Identification System

An aircraft engineering drawing must contain certain data, which is used to prove its validity and legality. All alterations to drawings must be made in accordance with a drawing amendment system, which will ensure amendment to design records. If an alteration is made, a new issue number and date must be allocated to the drawing.

To comply with legislation, procedures must be introduced to progressively amend the total definition of the product in terms of its associated list of drawings at specific issues. Each particular variant of a product and its state of modification must be identifiable in relation to the appropriate list of drawings.
