[QUOTE=Down3Green;16010326]Obviously as crew members, we have known about this for some time....I'm somewhat surprised it took this long to reach the light of day. QUOTE]

Not all things are made public, even though they may not be secrets. Initially came out as a flight crew notification on February 10, 2011, that the oxygen generators may have been rendered inoperative and to check the lavs in case of a rapid decompression.

Now official, issued March 8, 2011, Airworthiness Directive 2011-04-09, that mandates that the lav oxygen generators were to be discharged or removed completely.

The do create a great deal of heat when activated, my guess is that someone figured out the the bad guys could do something quite nasty with them.

About the third time that mechanicals have been found, from a security aspect, and not disclosed to the general public. These are not safety issues, but security issues.
