Crash threat

January 9, 2008

A Qantas 747 with 344 passengers on board could have faced
catastrophe after losing power from all four of its generators on
its descent into Bangkok on Monday.
...
The Australian Transport Safety Bureau said it had been told the
power from the main generators was lost 15 minutes away from
Bangkok.

"In this case it looks as if it has gone to the last stage of
emergency power for communication and navigation," Dr. Arvind
Sinha, director of aerospace at RMIT University in Melbourne, told
the Sydney Morning Herald. "After that it comes down to the skill
and experience of the crew." He added that the loss of all four
generators is "unheard of" but Murphy can and does find a way,
this time through a sink with a clogged drain in the first class
galley. ...

The sink is right over the electrical distribution unit and Boeing
engineers evidently considered the potential for leaks when they
put it there. A drip tray is installed to catch any overflow from
the sink but the tray on this aircraft was cracked.
