Interesting...
If the plane was heading into thunderstorms, and equatorial storms are the biggest there are, and the plane experienced catastrophic electrical failure, then I'm wondering if the weather radar was hit by lightning. That's the radar up-front in the cone and it's not shielded. If that was hit then the crew would be flying blind and unable to navigate around the super cells.
The A330 is a fly-by-wire craft which depends upon its electrics working in order to control the plane. There are redundant systems should the electrics go belly-up, including a manual control system.
However!
This got me thinking about the only other commercial crash of an Airbus I know about as it happened in Queens right after 9/11. That crash was bizarre and many thought it was a terrorist strike. It wasn't. That crash was caused when the pilot managed to cripple the manual control system causing the rudder and other control surfaces to break off the plane. I wonder if that isn't what happened here.
I know very little about planes so I might be talking out my ass, but I wonder if the A330 emergency controls aren't similar to the ones in the A300 and if that manual system isn't a weak point in the plane design. Looking around, I see
one guy who is a pilot has speculated a link between the two for the same reasons.
The thing is, I don't know what kind of maintenance the plane had in April. Did they do all the structural X-rays and other major work or was it a more routine service?
Ugh! Where's Claire?
