Technical Manual : Engineering Handbook Series for Aircraft Repair - General Manual for Structural Repair (ATOS) (TO 1-1A-1, NAVAIR 01-1A-1)

Technical Order (TO) 1-1A-1 is one of a series of manuals prepared to assist personnel engaged in the general maintenance and repair of military aircraft. This manual covers general aircraft structural repair. This is a Joint-Service manual and some information may be directed at one branch of the service and not the other. Wherever the text of the manual refers to Air Force technical orders for supportive information, refer to the comparable Navy documents (see Table 1). The satisfactory performance of aircraft requires continuous attention to maintenance and repair to maintain aircraft structural integrity. Improper maintenance and repair techniques can pose an immediate and potential danger. The reliability of aircraft depends on the quality of the design, as well as the workmanship used in making the repairs. It is important that maintenance and repair operations be made according to the best available techniques to eliminate, or at least minimize, possible failures.
