My APU is on FIRE (said in your best French accent)

Defective fan blades on General Electric CF34-3B1s should be taken out of service before another in-flight fire or engine failure occurs -- so says the NTSB, labeling the associated safety risks "unacceptably high."

Ok, so your APU is not on fire because of defective fan blade, however, saying "Oh my gosh, my left engine is on FIRE (in your best French accent) is much worse and not preferred...especially because the French play a role in Airbusness.

In its Mar. 5 recommendation letter, the safety board cites two previous failures, both involving Bombardier CRJ-200s. The first event occurred July 27, 2006, shortly after Air Nostrum Flight IB8174 departed Barcelona International. During climbout through 23,000 ft., the flight crew heard a loud bang and the aircraft experienced severe vibration. The No. 1 (left) engine fire warning continued for 9 min. 39 sec. and ended as the aircraft returned safely to the airport on one engine.

The second event occurred May 24, 2007, when an Atlantic Southeast Airlines flight was in cruise flight at 23,000 ft. The pilots also reported a loud bang and severe aircraft vibrations, and inspectors determined that the blade in the No. 2 (right) engine separated below the platform in the blade attachment area. The ASA flight diverted to Blountville, Tenn., landing without incident. The NTSB expressed concerned that the ASA blade fractured "early" in its service life - after only 4,717 cycles and 5,845 hours.

The CRJ just keeps giving more reasons to hate on it.
