The FAA has launched a new web site:
Lessons Learned From Transport Airplane Accidents
From the web site:
International commercial air travel has reached levels of safety and convenience which would have been unimaginable just a generation ago. Although almost always extremely tragic events, the lessons from accidents have played an important role in the process to continue improving this safety.
This Lessons Learned From Aviation Accidents library represents some of the most major accidents and their related lessons. The U. S. Federal Aviation Administration, with support from many others, plan to continue adding to this material on an annual basis. The objective is to populate the material with many more of the most historically significant, policy shaping accidents, in order that the lessons that can be learned from their review may be available to all users of the library.
