NW 757 Emergency Landing - MSP

Sun Jul 18, 2004 7:21 am

I have a friend flying BOS - MSP - SFO today on the red tail and he called from the MSP Worldclub to say he had a scary Landing in MSP. The pilots announced they would be landing on one engine, landed fast w/ a bounce, and were surrounded by emergency equipment for 10 mins before taxi to gate. Any word on what this was all about? He does not know much about aviation but knew he was on a 757. He said the pilots announced the 1 engine landing while they were already on approach and that right before that announcement he heard a fairly loud rhythmic noise that did not seem right coming from one of the engines. Any thoughts?

P.S. I saw the post about $29 flights from LAN - IAD this morning and went straight the airport. In DC for the evening having an unexpected dinner with friends!

I don't know.. I can't even check the status of any flights at nwa.com.. it seems there's a problem retrieving flight info on the website
It's funny when I tell people I love planes and they think I'm weird.

and that right before that announcement he heard a fairly loud rhythmic noise that did not seem right coming from one of the engines.

That sound would have been the hydraulic power transfer unit(PTU). In the event of a number 1(left) engine driven hydraulic pump(EDP) pressure loss the PTU uses hydraulic pressure from the number 2(right) EDP to pressurize the left hydraulic system. A shutdown of the number 1 engine would therefore cause the PTU to start operating and the sound it makes is a loud rhythmic growling noise that actually comes from the left main gear wheel well. This only happens with the left engine shutdown as ground steering and alternate braking are on the left hydraulic system.

This seems consistant w/ what my friend said. He said that before the pilot's announcement he thought there was a problem w/ the landing gear and didnt realize it was an engine until told (and then he assumed the sound must have been the engine),

Mike,

I was out spotting at MSP on Saturday afternoon. It was a little after three when I saw a NWA 757 land. Shortly after the 757 moved off the runway 12R/30L. I saw about 7-10 MSP fire truck race towards the jet. I couldn't see much because of the jet blast reflector were in the way. I did catch the reg. N527US. After about 3:30 PM the 757 moved off tarmac along with the fire trucks. I think were probably talking about the same jet. Thanks to pilottim747 for pointing this thread out.

Regards,

Ken

I wonder what happened to the bad engine? Do we have any way of knowing or does that info stay between the NW pilots and mechanics?
