A Boeing 737-300 has recently been forced to perform an emergency landing after an explosive depressurization due to a rather big hole in its fuselage. Reports suggested that some MRO (Maintenance; Repair; and Overhaul) operations had been outsourced to El Salvador, and might have caused such an accident.
However, the NTSB (National Transportation Safety Board) said that the last heavy « C » check – the last major MRO operation on the aircraft – was performed at the Dallas Southwest maintenance facilities in March 2010.
The TWU (Transport Workers Union) has condemned the use of aircraft repair stations outside the USA, calling on Congress and the Federal Aviation Administration to toughen the FAA’s oversight – Watch the video:
A Southwest Airlines Boeing 737-3H4 had been forced to make an emergency landing less than two years ago. Another B-737-3H4 has just had a 6′ hole in its fuselage during a flight causing sudden decompression, and emergency landing.
The NTSB is leading an investigation into exactly what happened to this Southwest Airlines flight – a 737 which had a hole come open during a flight from Phoenix to Sacramento at FL 360 (altitude: 36,000 feet that is to say almost 11 kilometers high). It was a harrowing experience for the passengers and the crew members. Watch the video:
