Oh, OOPS, I just threw my GPS-equipped underwear into the hotel washer....!!!!! 

 ::banghead::

NO BRAIN..........  NO PAIN..........

Bummer---hopefully with all the advances in technology it will be waterproof.

After looking at the new all-glass instrument panels at the heli-expo earlier this year, I now have an appreciation of what a dog feels like when watching TV.

Well I probably shouldn't throw this in here, as I can't recall the details, but I did read somewhere a few weeks back that there was some question about the initial certification??  That the gearbox needs to be capable of running a certain amount of time without any oil, and that somehow the first tests were not done to the proper levels??
 :(

That whole gearbox certification thing was about the S-92 that crashed in Canada a few weeks ago. They had a loss of oil and the reliability of the "run dry" test from Sikorsky has been called into question. (Very unbecoming of me---answering a technical question do'nt ya think..).

Whaaat? ? ?

What S-92 crashed?

Already?

Didn't they just build that aircraft? It's already crashing?   ::eek::

You guys are just full of bad news tonight, huh?!

In case you miss the link:
http://uk.news.yahoo.com/21/20090417/tuk-urgent-probe-into-copter-gearbox-6323e80.html

The checks had been done after a small chip of metallic debris had been found, 34 flying hours before the crash, on the gearbox metallic detector which is used to attract any bits of metal which can get into the system.

There was no description of the metal chip and is hard to evaluate without the hardware.
A chip could have been there for some time.  It could have just chipped off.
The maintenance group appears to have applied standard monitoring following detection.

Clearly mechanics will have to be a lot more aggressive in the future.
Hardened gears will have to be treated with kid gloves.......
