NATTS AEROSPACE NDT TRAINING- ( NAS -410 ) 

The National Aerospace Standard – 410 (NAS-410) is an established standard that outlines the minimum qualification requirements for personnel that perform non destructive testing On Aeronautical & Aerospace Components

Nondestructive testing (NDT) is important for making sure protection, fine and integrity of crucial aerospace components, assemblies and systems at some stage in production and overhaul, preservation inspections of aircrafts.

Inspection of aerospace components and structures is carried out for the duration of various degrees of producing and preservation (overhaul) inspections based totally on criticality of the components and particular plane structural first-class requirements.

NAS 410  : NATIONAL AEROSPACE STANDARD

For many years, aerospace and defense related military or government contracts required NDT personnel qualifications in accordance with MIL-STD-410E. It was replaced in the 1990’s by NAS 410.

Initially published in May, 1996. Revision 1 was issued in June, 2002; Revision 2 was issued in February, 2003 introducing significant change in the training of Liquid Penetrant Testing and Magnetic Particle Testing personnel.

Training for each of these methods was increased to 16 hours each for Level 1 and Level 2 for a total of 32 hours for Level 2 qualification. Additionally, Revision 2 changed the re-certification period for Level 1 and 2 from three (3) years to five (5) years intervals.

NAS 410 Revision 3 (current version) completely revised the standard in March, 2008 and is considered technically equivalent to the European standard EN 4179 entitled Qualification and Approval of Personnel for Non-destructive Testing.

Table 1 and Table 2 provide training and experience requirements for Level 1 & 2 personnel.
