Investigators find cracks in second Dreamliner engine
(CNN) -- Just two months after an engine cracked and failed during test aboard a Boeing 787, federal plane inspectors have found a second engine problem on a different Dreamliner, the National Transportation Safety Board announced.
The NTSB identified the problem as a cracked fan midshaft on a Dreamliner General Electric GEnx-1B turbofan engine, the group said in a written statement posted on its website Thursday. The 787 had not yet flown when investigators identified the engine problem, investigators said.
Inspectors uncovered the cracked second engine during an inspection of all in-service engines of that type, the NTSB said. The statement included no further details of the discovery. The NTSB, which investigates all U.S. civil aviation accidents, said its investigation of the engine troubles is continuing.

Old News...but...
FAA has issued an AD for the GEs. Expensive inspection to be carried out every 90 days. GE does have a fix. The shafts were redesigned which means that operators could remove the engines and have the new shafts installed...or..be subject to the inspection AD.
Messy.

Indeed Payscale, e.g. does anybody else remember the dual engine failure that occurred to a 'Air Europe' B737-300 (a new type, at the time) in 1987, and which was also followed by a number of similar engine failure events at other airlines operating that engine type!?

I don't mean to be morose but a A320 crashed and killed all on board during a demo flight. And it was partly due to the complex flight control system, something Airbus were raving about at the time (come to think of it they haven't stopped raving about it). Nevertheless, thousands of A320s have been sold. I think MSN numbers are at 5000+.
