Don't please start an anti dc-9 trip here, but I'm just wondering - last Friday, I flew from Lousiville to Detroit - Flight was late, maintenance issues (originated in MSP) - today , I flew from Detroit to Louisville - flight was late, maintenance issues

Are these great old birds finally getting tired?

I doubt it. I have had MX problems on just about every trip I've gone on, on at least one leg. (On UA, DL, etc.) So I think that minor MX problems are quite common, and they do indeed cause delays sometimes. You just caught two planes that had a MX problem.

Heard from a friend a DC-9 lost an engine here in Orlando about a month ago, anyone have any info on that? 10 seconds or so after takeoff, large fireball shot out apparently. From what I heard it was pretty scary.

From what I've heard on this site, the cycles on the NW Diesel 9 fleet are such that they're viable through 2010 and beyond.

Like any aircraft, their maintenance record will be as good as the people who maintain them. Older aircraft do tend to have a marginally higher MX cancellation rate however.

As an example...guess which aircraft in the DHL American freighter fleet has the best dispatch reliability? You guessed it: the Diesel 9.

I will agree that the NW DC9s are getting tired... I kind of wonder if they will make it 4 more years? and now the big question. What will they replace them with?  duck

NW has enough of them that keeping them flying isn't really an issue. They cycle them through enough, and their DC9 maintanence is good enough, that they do just fine for reliability.

As for replacing them, E-190s and E-170s, the 190s to be opperated by NW mainline, and the 170's to be opperated by fully owned NW subsidiary Compass, or atleast that's the plan so far.

And if you think their DC-9s have been around the block, some of NW's DC10's are past 100,000 flight hours.

Either way, NW is a crumby airline. Who knows why it was actually late, they blame MX no matter what the cause of the delay is. I tell people the best thing about my NW WorldPerks frequent flyer miles is that I can use them to buy tickets on Continental and Delta.

Better then most blaming it on weather so they can get out of vouchers. There no different the CO or DL.

How do you account for their on-time rankings continually in the top third of the industry and the highest load factor in the industry. Ohers must think differently than you!

I enjoyed my single NWA flight to/from BWI on NWA. We had one MX delay for an hr and a half, and it was on a 757. We had engine problem on the left side I think it was. No DC-9 there.

Usually if it is weather it IS, no airline would lie about it because a passenger would raise a big "fit" how its sunny here when its raining according to them.

Profitablity was not under discussion, but whether Northwest was a crumby airline. I was pointing out if they have the highest load factors in the industry then most peoplr do not feel that way. How did that segue into profitability?

Maybe you should do some research before you make a post like that, many of these so called scabs were former NW mechanics before first round of layoff that essentually came back to NW. Secondly, the managers of the maintnance are not scabs. Finally, ask just about any NW pilot, and they will tell you these so called scabs work harder, and do a better job then the guys that were there already. Also the DC-9 has a higher on-time dispatch rate then the A320 series.

Well thats about as harsh as a side remark as I've heard. NW and all other airlines including many favorite Southwest has mx issues. Heck I was on a Southwest (unfortunately) flight from MDW-DTW and the flight was delayed 1 1/2 hrs after boarding and de-planing for mx issues.

If they are doing such a great job why all the delays and cancellations?
In MX circles, the word gets out how screwed up things are at NWA.

No offense, but maybe you should get back to spotting and leave the technical side to the ones who are in the know...

You mean like one of the higher on-time percentages of US Airlines.

And no offense, but when you have someone working for the airline under the same roof, you think they might know more then those at another airline.

As for statistics WN isnt really much better, in fact a little worse in a couple categories.

April 2006 Northwest:
On-Time= 82.14%
Air Carrier Delay= 6.47%
Weather Delay= .91%
National Air Traffic Control System Delay= 6.8%
Security Delay:= .02%
Aircraft Arriving Late= 2.88%
Cancelled= .57%
Diverted= .20%

April 2006 Southwest:
On-Time= 79.99%
Air Carrier Delay= 4.72%
Weather Delay= .36%
National Air Traffic Control System Delay= 3.4%
Security Delay= .07%
Aircraft Arriving Late= 11.19%
Cancelled .45%
Diverted= .16%

I like that statement. A lot of people don't understand that.

Although I have disagreed with Burnsie a couple of times, he really is quite knowllegable abour NWA and the airline industry. On the other hand I think you have a hidden agenda.

I'm a third year NW silver elite, and I've flown NW about 30 times or so over the past three years. I end up on the DC-9 a lot, and I have never had an MX delay on the DC-9. However, its happened about 4 times on the A32X series, and it seems its always some flakey problem with the computer or the electrical system. I think with the DC-9, its a case of there being less that can go wrong due to the older technology. It does not suprise me at all to learn that the DC-9 has a better dispatch rate than the airbus.
