Dear Readers,

We are happy to publish on our Website a paper by Richard GASSET, NADCAP Supplier Voting Member of Lisi Aerospace, which was published in the June 2012 PRI-NADCAP Non-Destructive Newsletter issue that you may read using the following link:

It is known that 85 % of aircraft accidents have human causes. Could we imagine that 85 % of the defective parts that get the “Pass” tick after an NDT are accepted due to human errors? This paper fingers out very currently met situations…that, when added to each other, may make us think so!

We hope that this paper will be of some interest for you and bring you a top - quality information.

(updated in September 2015)

We got an interesting question, a very practical and “basic” one. Basic, yes, at first sight. In fact, not that basic at all!!!

The question came as: what is a good indicator that the magnetic particle concentration in a magnetic ink was excessive?

March 2015

Penetrant Testing and Magnetic Particle Testing materials are made of industrial-grade ingredients. There would be no technical advantage to using analytical-grade substances, the costs of which would be exorbitant and unjustified. Therefore, some impurities are to be found in the raw materials and in the finished products. However, are you sure that this is the sole source of impurities?
