43、ation of this standard and the overall administration of the qualification and certification program. 4.4.2 NATIONAL AEROSPACE NDT BOARD (NANDTB) The organization has a constitution, a deciding entity, and governed according to administrative and working procedures. The voting members in the decidin

44、g entity are NDT Level 3 personnel and are from participating prime contractors or type certificate holders as a minimum. Other members may be co-opted as voting or non-voting members as necessary to support the NANDTB. Regulatory agencies for civilian and/or defense have the right to be included as
