I am very uneasy about this. Long before any novel material is decided upon for production of civil aircraft repair should have been investigated and repairs exhaustively tested in lab and field conditions. For repairs carried out ex-factory or specialist repair workshop, the means of carrying out such repairs should have been tested at remote non-specialised workshops.
That it has taken almost four months to decide how to do it is deeply concerning and implies a serious oversight in the design and production programme. Certainly the method of repair should be in the public domain, including all test data taken, confidential proprietary information or not. It is only by publishing the full details to the wider engineering world that peers can comment. If there is a paper, it sounds as though it won't be peer-reviewed and won't have had any proper field trial.
