CS 27.605  Fabrication methods

ED Decision 2003/15/RM

(a)     The methods of fabrication used must produce consistently sound structures. If a fabrication process (such as gluing, spot welding, or heat-treating) requires close control to reach this objective, the process must be performed according to an approved process specification.

(b)     Each new aircraft fabrication method must be substantiated by a test program.
