Apparently for GE it is more economic / convenient to pick up the tab & get it over ASAP, then to explain the NTSB, FAA, public, Boeing, BA, customer base what exactly happened and why for the next 10 years.
This will be the most expensive "repair" to a Boeing 777 ever. Similar to the exploded engine QF A380 repair. That one was less damaged & new.
This paper is also on an NTSB desk. It is better to discuss an aircraft already back in flight, than one on public display in Las Vegas. Common sense.
Keesje: since you obviously know so much about not only the cost of airplane repairs but also the inside scoop on what major corporations are doing to deceive their sophisticated customers and regulators about the true (according to you) defective nature of their products, I suggest you hire yourself out as a consultant. If, as you suggest, these companies are willing to pay tens of millions of dollars for repairs in excess of the cost of replacement just to cover over these issues, your inside information about this will be worth millions. Good Luck.
