23、teel brackets”), or assembly. These are sometimes referred to in the industry as “technique sheets” or “data cards”. Such work instructions are based on procedures defined in 3.27. 3.35 WRITTEN Retrievable electronic or hard copy. 3.36 WRITTEN PRACTICE A document that describes an employers requirem

The Responsible level 3 shall be responsible for implement

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

45、 observer members.
