NTSB calls for changes in FAA`s airliner design certification process
25 April 2006

The NTSB published a report, considering lessons learned about certification issues in four major accidents investigated by the Board between 1994 and 2001 that, collectively, accounted for 60 percent of the air carrier fatalities in that period. Overall, the Board found that the FAA`s certification process is sound and produces a high level of safety. However, the Board does make three recommendations for improving the process, dealing with documenting the identification of safety-critical systems, ensuring that the identification process includes evaluation of structural failures and human/airplane system interaction failures, and assessing safety-critical systems throughout the life of the aircraft.
