NTSB Directive Contradicts Boeing Statement
On April 25, the NTSB released information about the April 1 Southwest Airlines Boeing 737-300 fuselage incident where the rupture in the fuselage caused depressurization and forced pilots to make an emergency landing in Yuma.
From the release
The NTSB Materials Laboratory work is actively conducting additional inspections and examinations in the following areas:
Of 136 airplanes inspected worldwide four had crack indications at a single rivet and one plane was found to have crack indications at two rivets.
In spite of these findings, Boeing Chief Executive Jim McNerney told Reuters“I think the initial data that I think we’re all seeing is suggesting a possible workmanship issue on an airplane, rather than a design issue across a fleet of airplanes.”
If Boeing believes that the problem was workmanship on a single plane, then how did other planes reveal conditions precursing the same type of rupture incident as was incurred on Southwest Airlines Flight 812?
