Wheel Falls Off Northwest Plane

Fri Dec 16, 2005 4:25 am

I read this story in The Commercial Appeal (Memphis) today. I can't find a link to the story on their website so I'll type it because it is short.

"A landing gear wheel fell off a NW DC-9 after it landed in Memphis early Wed. afternoon and bounced down the taxiway beside the plane. Shop workers estimated the tire weighed 200 pounds. The DC9 taxied to the gate normally, and all 117 passengers exited through the loading bridge. No one was hurt."

Strange story. I wonder what the pilots and pax thought as the wheel bounced down the taxiway beside the aircraft!

[hint to NW]Planes are so old the bolts are falling off - replace [/hint to NW]

Reminds me of a little story
A nosewheel fell off a GF Tristar on takeoff from LHR in 1978 bound for BAH. During the six hour night flight the Managers all got together to decide what to do. There was a slight problem because in those days BAH was very busy at 0530 when it was due to land with B747-200 departing.
Anyway about 0500 the Ops Manager made a decision..Let it land.. he said. The rest of us wondered what else it was going to do! The landing was uneventful and it taxied to the gate.

Great, as you can see from my handle, I fly NWA a lot - can't wait for the wheels to start coming off (literally)

Such events can occur for a number of reasons, often human error. Overtightened or undertightened wheel bolts, damaged wheel or bolts/lugs, failure to spot a problem, brake problems, metal fatague (a factor in older a/c) and so on. I hope they determine the cause soon.

And you do realize that is was possible that a contractor put it on as well?

Its HIGHLY unlikely that a wheel assy falling off had ANYTHING to do with the age of the bird. Its much more likely that a mechanic who is unfamiliar with standard maintenance practices screwed up. Take that however you want.

It's only one wheel, what's the big deal? The plane has 5 others. I mean, it's not like it was a nosewheel that was sideways or something.  duck

Identical? The ATR lost a nose wheel assembly. The 737 broke a main axel. What is identical is that in both cases the tire that remained could not take the extra load and failed.

Just heard Doug speak of this Wednesday. He said that basically they are offering the ALPA NW pilots the first 500 pilot jobs to currently furloughed NW pilots to fly the new 70 and 100 seat range aircraft under what NW is calling "NEWCO," very similar to what they did with Pinnacle back in 1996. (Pinnacle believes that NW is not as interested in retaining their business as they should be - you would think they would go with Pinnacle before anyone else but you never know nowadays.)

They are currently considering the Embarer 170/190 (perhaps even the 195) to the CRJ 700/900 combo. However the pilot's scope clause is causing the two parties to disagree on how much salary these pilots will get and so NW has an RFP out with basically every commuter airline capable of offering these types of service (Mesa Air Group obviously in the front as they already operate CRJ 700 adn 900's for HP.)

If the pilots agree with NW and NEWCO is launched, it will depend upon how creative they the management can get as well as how flexible the courts will allow them to place an order for 100+ airframes, but Bombardier needs the CRJ 700/900 business very bad right now so highly attractive financing and terms might be able to be obtained. If NW decides to outsource the contract (and ALPA pilots at NW don't strike) than the prospect of retiring the DC-9's sooner may be feasible, but it all just depends upon various and numerous variables.

I agree, this happened years ago at NWA. We would get maintenance updates(sorry I can't remember the name NWA used) we called them read and sign updates. I do remember seeing this update. NWA found that the wheel assembly was installed improperly. They also found it was a 3rd party vendor that installed the wheel assembly last. Who's to blame on this one, I don't know but it makes you think.

Several years ago a NW DC-9 bound for DTW lost a main gear wheel on takeoff at MDW. The tire rolled off the end of the runway, through the chain link fence, bounced off of a car.

Needless to say those wheel assemblies have some momentum for sure!

Were the superior union mechanics off that day?

Gang, this really is no big deal structurally for the aircraft. Aircraft are, by their vrey nature, designed with fail-safe standards incorporated. The loss of one (or more) wheels is not a catastrophic event. Many aircraft have landed with blown/shredded/missing tires or lost them on taxi and been just fine after the tire gets replaced.

Unless it was mechanical/structural failure of some kind, the most likely scenario is the pre-torque/final-torque values were not followed properly when the tire was last installed.

Because its not a big deal? Tires blow on landing alot. They are designed to land missing a tire or 2.

Yeah, I remember when that happened. It only got five seconds on the news, and nobody made a big deal about it. That tire weighed more than I do, and could easily have killed a driver or pedestrian.

The same thing happened here in LIT in 1994 to a WN 737. This is the NTSB report.
