7 major airlines outsourcing 40% of their maintenance

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:

2nd fuselage with a hole – Southwest Airlines aircraft grounded

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:

Enigma of Yuri Gagarin’s death on March 27 – 43 years ago

The cosmonaut Yuri Gagarin – the 1st man to have travelled into outer space on his Vostok 1 spacecraft on April 12, 1961 – died on March 27 1968. However, the precise cause of the jet crash remains uncertain.

Colonel Gagarin and his instructor Vladimir Seryogin (as Gagarin, director of the Star City, had to obtain his fighter pilot rating again), flew a MiG-15 Midget that day, and they should not have kept the fuel tanks under their jet. As the spin turned into a deadly crash, it has been suggested since 1986 that the afterburner turbulence of a Sukhoi Su-11 Fishpot-C interceptor aircraft could have caused the MiG-15 to go out of control.

The MiG-15 had first been designed to intercept USAF nuclear-capable B-29s.

Some governmental documents were declassified in 2003. They revealed that in addition to the official investigations, the KGB tried to advance a new line of inquiry. Since then, it has been deemed that the accident could not be due to any conspiracy theory. Though little is certain about this mistery, you can click on the frame below to read further information:
