A few paragraphs from what the NYT wrote. Link is at the very begining of this thread.
Critically, in the case of the NG, Boeing had already developed the software fix well before the Turkish Airlines crash, including it on new planes starting in 2006 and offering it as an optional update on hundreds of other aircraft. But for some older jets, including the one that crashed near Amsterdam, the update wouldn't work, and Boeing did not develop a compatible version until after the accident.
Five years before the Turkish Airlines crash, Boeing was aware that a sensor malfunction could idle the engines improperly, but the company decided it wasn't a safety concern, the Dutch investigators wrote.
The safeguard was available in 2006, but the change wouldn't work on some 737 NG models, like the Turkish Airlines plane, that used an autothrottle computer made by a different company. After the 2009 crash, Boeing developed a version of the update compatible with those computers, and the F.A.A. required airlines to install it.
