CRJ 200 gear up landing (in Spain)

[dbert]

Per Bombardier message.

A CRJ200 Regional Jet was involved in a landing incident in Barcelona, Spain, January 24, 2007. The airplane landed with all three landing gears retracted. The flight was en-route to Barcelona from Valladolid, and was carrying 40 passengers and 4 crewmembers. The incident occurred at 15:10 local time. Two (2) passengers were slightly injured during the post landing ground evacuation.

The Civil Aviation Accident and Incident Investigation Commission (CIAIAC) of Spain will investigate. Bombardier Aerospace and the Transportation Safety Board of Canada will support the CIAIAC investigation as required.

Should any further relevant information become available through the course of the CIAIAC investigation, Bombardier Aerospace will advise all operators.

Other than failure to select the gear down (ignoring horn and flashing amber UP indication), what could possibly hang up all three gear?

I assume they landed gear up after exhuasting all options, I doubt they just forgot (You'd have to be deaf).

Failure of the electrical gear handle switch might cause this, not sure why the emergency system didn't work (mis-rigged?).

Failure of #2 & #3 Hyd could cause failure of both normal and emergency (the emergency extend is supposed to use #2, at least for the mains)

So you’re going with the theory that there was a failure of both the normal and the alternate extension system on all three gear, or they lost two of the three aircraft hydraulic systems simultaneously? Talk about having a bad day.
The mains use system two for lock assist. Typically the alternate extension works fine even without assist from system two.
