Thousands of faulty fan blades found in CF34s
The NTSB last month sent recommendations to the FAA and Transport Canada to address a safety concern raised by two engine failures on Bombardier CRJ200s.

The NTSB last month sent recommendations to the FAA and Transport Canada to address a safety concern raised by two engine failures on Bombardier CRJ200s. The Board has determined that a flaw during the manufacturing process for fan blades led to the failure of the GE CF34-3B1 turbofans, and it wants procedures established to remove the suspect blades before another incident occurs.

In both cases–a July 27, 2006, engine failure on an Air Nostrum CRJ shortly after takeoff from Barcelona, Spain, and a May 24, 2007, engine failure on an Atlantic Southeast Airlines CRJ while in cruise flight from Syracuse to Atlanta–a fan blade fractured, causing a loud bang, severe vibration and in one case an engine fire. Both flight crews declared emergencies and landed safely with no injuries.
