Incident: Northwest A333 over East China Sea on Jun 23rd 2009, unreliable airspeed
​

Northwest Airlines Airbus A330-300, registration N805NW performing flight NW-8 from Hong Kong (China) to Tokyo Narita (Japan), was enroute overhead the East China Sea, when the crew noticed a sharp drop of the indicated outside temperature followed by the loss of the air data reference system, disconnection of autopilot and autothrust system along with the loss of speed and altitude information. The flight crew used the stand by systems and was able to restore the primary data. The airplane landed safely in Tokyo Narita.

The NTSB is investigating, the flight data recorders have been retrieved, the aircraft condition monitoring system messages, crew statements and weather information are being collected by NTSB investigators.

The NTSB reported, that a very similiar incident happened on May 19th to a TAM Airbus A330-200.

i don't have tons of experience with pitot tubes, but isn't the real issue here flying in thunderstorms? The weather description matches that of a severe thunderstorm, the same as the AF weather situation.

The crew members initials match the flight....I would not have sent this in an email. Delta legal is going to crucify him.

if it ain't boeing, i ain't going.

Like you really have a choice...It's only democratic when you have finally hung up your wings.

For ********************s and grins how about "without a table I'm not able"

My sentiments exactly. Notice how the letter writer only mentions "rain". He is avoiding the elephant in the room.

When the radar shows red below and green and yellow at your flight level, you are trying to top a TRW. Why not just 20 degrees right for weather (oceanic or not).

Similar

While a different class of aircraft, the Beechjet fleet suffered through this issue. I personally experienced a failure of 2 of the 3 airspeed indicators at FL390. We were just in the tops. We could barely see ice crystals. Smooth ride.

For our fleet they discovered that the front of the tube was heated and the base was heated, but the 90 degree bend was not. Thus the front would heat the ice just enough to melt it an then it froze in the bend. During our descent through about FL210, it melted and the two failed airspeeds came back to normal.

From the news reports today (and we all know how accurate they are) pitot tube problems are relatively common on all airplanes accoriding to the NTSB databse.

Baja,
You should really delete your post. Did your friend know that you were going to post it on a public message board? It isn't properly de-identified and there may be legal ramifications.

I agree.

This is basically the NASAP report itself, on a public forum, with names in it.

That said, if I were in the crew I wouldn't have sent it out either.

BS.

ASI's don't "roll back" to zero from ice.

You been shopping too much at Walmart.

ONE improperly maintained jack screw fails out of all the basic9 and 80series ac.

It wouldn't have failed completely BTW even on that flight had they not kept screwing with the damn thing once it was jammed...and just did a precautionary landing with a slightly less than ideal trim setting...

So give me a break...

And who says the video game aircraft are immune to hard overs?

We had one fail on a DC-10 due to cheap Chinese parts not meeting the standards that it was supposed to and jammed up.

After rereading this I only see where initials were used...If you would have clicked the link provided by Crunk you would have read the following:

An e-mail is circulating in the Internet presumably from the copilot of the flight describing the event. The authenticity of the e-mail could not be entirely verified, there are indications suggesting, that the e-mail is authentic, and there are some indications to the contrary. The e-mail began to circulate before the NTSB issued their press release.

Delta Airlines as parent company of Northwest Airlines are unable to confirm the authenticity of the e-mail or sequence of events described in the e-mail.

So please give it a rest. When I received the email I was one of many on the list and the info look to be of good value to those by Airbus aircraft. If DAL legal wants to get this guy I'm sure they will have a MUCH better chance by following the chain in the email...not sifting through flightinfo.com users. If the mod's want to take this - it's fine w/ me. But I'm NOT going to ask for its removal.

Baja.

I can verify the non verification justification.

It gives the airline, the date, the time, the aircraft type, and in the last paragraph it uses a full first name. Oh yeah, no social security numbers or blood types, so I guess no one could possibly be identified.

I don't know what link you're talking about, but in your original post, you say that you received the e-mail from a friend who is a retired NWA pilot. There is no mention of a mailing list.

Hope you never find yourself on the other end of a situation like this. You should really delete the post.

Tref.....As the link that Crunk posted says:
http://www.avherald.com/h?article=41bb9740&opt=0

This email might be a hoax. When I received the email it was from a friend who is current NWA. The email was forwarded to 50+ airline types, myself included. The original email has full names and dates etc. The link (shown above) states that DAL is aware of the email and has no comment. All I'm saying is that DAL legal has ALL the info they need if they are interested in this at all. And my posting an edited copy of the email here for other airbus drivers to read and possibly learn from shouldn't be getting your panties in a wad. If you are so hellbent on getting this thread removed send an email to a Mod...I don't care. Just ease up a little....

Baja.

They do if there is a drain hole still open aft of the ice.
