Delta MD-88 at Atlanta, wheel fire after landing

..been involved with the design of a RP Bulkhead lately and judging by the amount of forces acting on it (More so than a Barrel of a fuse) and the Designers complete avoidance of penetrations in it apart from Cables and Hydrauls, I assumed falsely that all RP Bulkheads were built this way and am surprised to find Pax doors in them.

Specifically this one: –

So, that door is actually in the Rear Pressure Bulkhead then? I didn’t know this at all.

The 1-11 did, I do not know the MD/DC or the 727 so I can’t comment.

Americans… shoot first, questions later. No time to aim.

Ok it is a brake fire so why the hell are they flooding the stbd engine and inside the tailcone??:mad:

You can find pictures of the MD 80 rear door here

The tailcone does jettison as an emergency exit. It has an arming handle on the rear entry door either above or below the door handle (long time since i did the course!) I believe jettisoning the tailcone allows the rear door to continue to be used as an emergency exit in the event of a wheels-up/belly landing (you could exit across the now-horizontal stairs)

On the vid, an inflatable chute comes out of the Cone area. Why’s that then?

1. In the lower aft fuselage, forward of the rear airstair.
2. It will more than likely be a plug-type door, it opens into the cabin.

The Boeing 727 also has a rear entry door.

Ta.
On 1), the intake for it is still at the root of the fin though?
On 2), Rear Entry doors, no I don’t think I’m talking about the “Normal” rear entry doors which 727 (And other types) had, they came down with stairs attached. The 727 couldn’t have had a tailcone door as there is a JT8D lump in the way. I’ve never heard of a door in the RP Bulkhead until this weekend.
Structuraly that must be a PITA.

Thanks.
2 points here which I didn’t know about, at all.
1) Where is the APU on the MD80’s?
2) What kind of door is in the Rear Pressure Bulkhead to allow pax escape?
I’ve never known a door in the Bulkhead before, who (Makers) else has them?

Tailcones generally contain the APU but that one looked hollow? Maybe the APU was still attached inside and the final cone was jetisoned in order to let the fire crew get to the inside.
.

The DC-9/MD-80’s apu is not in the tail cone.

Why did the tail cone detatch?

The tail cone can be detatched when selected during an emergency evacuation

If the aircraft ends up on its belly the rear airstair will not open so the passengers can still evacuate out the back.

I’m sure some Md80 drivers will be along soon but I think the Tailcone was jetisoned. It certainly jumped off rather than fell. Only 4 bolts hold the cone on, at approx. 4,8,10 and 2 oclock.

Correct, it is certainly nothing to do with evac. There is a massive Rear Pressure Bulkhead at the back of the Pax cabin.
And yes, a lot of attention was paid to Stbd Engine but I suspect smoke got into it via the inlet and was passing through…so from the rear it could have looked like a fire.

However the slide was not deployed. Maybe the light load of the flight enabled the flight attendant in the aft to redirect passengers to the aft service door on the left side of the aircraft.

Just a guess.

I assume the slide pack is the yellow “box” on the lower frame?

I think there might be a little bit more to this than the news will have you believe!! I agree with you, the tail cone detachment is most peculiar – and has nothing to do with emergency evacuation. It just simply fell off!! The rear air stair on the MD-80´s series is way below the part that fell off. Also of note is the fact that the second fire truck on the scene pays particular attention to the right hand engine, hosing it down very throughly like it is on fire, but leaves the left engine alone!

Most peculiar!

I believe it’s an emergency exit on the MD-80’s.

The MD-88 involved was N941DL and this incident happened after the landing from flight DL2284 from Pittsburgh.
