Is that a request for the link to the Flash airlines 737 crash? If so, I can't find it now.

There were two investigations. As nearly all of the passengers were French, it was investiogated by the French BEA backed up by the NTSB, as well as the Egyptian Ministry of Civil Aviation. The two reports were published concurrently and were different. The French report concentrated on human factors, the Egyptian report concentrated on the technical aspects and was leaning towards a control malfunction.

The French/NTSB report said that it was likely that once the PF (the commander) had lost spatial orientation due to a slow scan, he then rolled the aircraft to about 150 degrees of bank and about 30 degrees nose down, the attitude in which the aircraft impacted the sea. The investigation concluded that is was probable that once disorientated, the PF reverted to type and tried to make tha AI look like what he would expect to see if he was flying level on a Russian style AI. Fatige was also mentioned as a factor. The report was also critical of Flash Airlines and the Egyptian regulation.

The Egyptian report said that the probable cause was an autopilot failure exacerbated by an aileron circuit jam and that had found evidence in the wreckage to support their view.

The two authorities disagreed heavily, and still do it appears. About three years ago, both reports were available on line to read. However, now the link to the French report doen't work and you can only now view the Egyptian factual report which concentrates on the technical aspects with no comment on probable cause, interestingly through a BEA link.

The Egyptian report can be read here http://www.bea-fr.org/docspa/2004/su...-f040103pa.pdf It's over a thousand pages and 37mb.

The French/NTSB report could be read here http://www.bea-fr.org/francais/actua...o20060325.html but it's been removed.

Interesting.
