Will we ever see another a/c like the MD-80 again?

[CA1900]

Yup -- one screw. Here's an NTSB animation of how the system works, and what happened in the Alaska accident:

What makes you think they were on acid? What is wrong with the plane?

My airport car had a sticker in the window that said: "If it ain't Boeing, I ain't going"!

Enough said!

It has been 6 years, so correct me if I have forgotten. But there is a primary trim and secondary trim. I know there is two motors. I thought there was two jack screws.

Two motors, one jackscrew. No redundancy.

 

[Flopgut]

Cal looked after the jackscrews. The story goes there were TI mechs that thought they needed extra effort and their additional attention became common practice at the Hobby MX hangar.

Bigger problem with being based on a DC-9 type certificate is the pay rates are already established. If that weren't the case I think the 717 would be more prevalent than EMBs.

It's been six years for me too(still furloughed) but I think there were several ways to trim but only one jackscrew. At my old airline in STL we had a previous AK 80 that happened to be the only one they found with a ungreased screw to comply with the emergency AD after the accident. Lesson is grease the screw.

But draggin piece of FOD. Took me two hands and full attention to drive it on autopilot, weird to land...just did not like it. 73 much more user friendly.

Heyas,

DC-9-30 with the -15 engines

Best. Airplane. Ever.

Nu

Hear.. Hear.. (or is it Here.. Here.. not sure).....

Sadly, they're all but non-existant on the line nowadays as the -9's have been deemed "most efficient" by dum-dom and sissy-scott... Alas...

 

[Tristar]

Never flew it, but hated riding in them. Nothing like having brake chatter that would loosen your fillings - though I've noticed it doesn't seem as common any more. Did they engineer yet another solution for a Douglas aircraft in the field?

[DC-10: Built in Long Beach, Engineered in the field. The WHAT failed?! Dang, we never though of that! Crap, we'd better fix it!]

 

[pilotyip]

15's on a 15F

Hear.. Hear.. (or is it Here.. Here.. not sure).....

Now that would be the bird

IIRC 1 jack screw but 2 trim motors. The accident was a result of improper lubrication. Besides that the DC-9 have been flying for 40 years. Bad design...I don't think so Tim.

 

[Fubijaakr]

Sure, but that doesn't change the fact that its a single point operating system for a critical flight control. Plus the lubrication intervals vary wildly between operators, with the FAA's blessing.

You just described many airplanes, from small to large.

Is that sort of like having three hydraulic sources to only one rudder pcu?

What about a dual magneto with one cam driving 2 sets of points? Guess what, that one cam has only one little screw holding it in place. If it comes loose, your a glider pilot in the single engine applications.

High wing Cessna has one bolt holding the wing strut on, if the bolt breaks, you will be auto rotating.

How many Cessna's have had a wing failure due to bolt failure?

 

[Colonel Savage]

I don't think was ever a DC-9-10F, the DC-9-10 combi version was called the DC-9-15F. The difference was the 10 had one over wing exit per side, the 15 had two over wing exits per side. BTW the 10 was was a real hot rod

You may have me on a technical point. What ever ABX had 22 years ago is what I flew. And you're right, it was a hot rod!

My dad used to say "Screw the geese!" when we lived under a flyway. What a mess!

 

[727C47]

forget the MD-80,bring back the 727 !!!!!!!!!!!!!!!

 

[PHXFLYR]

Now your talking !!!! ....

[rajflyboy]

Steam in the cockpit. MD 80 cockpits are older than Norfolk and Southern

 

[pilotyip]

B-24?

Why the B-24 shadow in your avitar?
