tail cones on MD-80s

Thu Jan 23, 2020 3:13 am

When the MD-80s first came out in 1979 the tail cones were pointed.Later on the MD 80s had the screwdriver shaped tail cone.When American Airlines started taking
delivery of their MD-80s in 1983 were they delivered with the pointed tail cone,when did Mcdonnell Douglas switch to the screwdriver tail cone.

According to prior threads, the change seems to have happened sometime in the mid to late 1980s.

Standard since the MD-87. I recall an old airliner book from the 90s claiming AA manufactured their own screwdriver tailbones for retrofit to the older fleet. Tailcone became standard on new deliveries later in the production run for all models.

AA TUL Mx base did indeed manufacture and retrofit their -82 and -83. Those guys and gals knew everything about that plane and were very proud of it.

I believe the change occurred in January of 1988.
Did you know that a Boeing 717-200 is really a McDonnell Douglas MD95-30? ;-)

The screwdriver tailcone was on the first MD-88 (N909DL) when it was delivered in Dec. 1987. IIRC, all of Delta's MD-82s (901-908) delivered in 1987 had the old tailcone.

For flight attendants, it didn’t matter. Emergency evacuation procedures were the same.

Were those MD-82s later upgraded to MD-88 standard? As much of a US airline fleet nut I've been over the decades "Delta MD-82" rings unfamiliar to me. Thanks

Yes, the first Delta MD-80s were delivered as 82s but were quickly upgraded to 88 standard.

Thanks for the reminder. Even my personal online fleet page for Delta shows those first 8 airframes as "cvtd DC-9-82" but I wrote that original text file over 30 years ago...guess my memory just purged that detail!

What was the difference between having the tailcone and having the screwdriver on those MD80s? Was it related to performance?

Brochures and other sources claimed a reduction of fuel-burn of up to 1% due to the installation of the screwdriver tail-cone.

Btw, were the MD-82s delivered to Delta equipped with EFIS cockpits or were they retrofitted during the MD-88 conversion?

No, EFIS and the EOAP (Electronic Overhead Annunciator Panel) were added as part of the mod.

Out of curiosity, were any of Continental’s or USAir’s -82s ever retrofitted with the screwdriver tailcone? I know that US didn’t have that many in their fleet, but CO seemed to have a substantial amount before being replaced by the 737s.

I vaguely remember an airline I used to work for was doing some testing for a company
for an aftermarket MD tailcone and ran some tests using DC-9-30 aircraft
and the screwdriver tailcone. I remember a few DC-9-30's running around for a short time
with the MD tailcone I wish I had taken a few pictures!

Can't say for sure...I spotted them during their respective careers and don't remember CO or US with screwdrivers. A good option would be to search this site for photos of them and see.

Personally, I never saw an USAir MD-80 with the newer cone, but I saw photos of MD-80s of Continental Airlines with the upgraded cones. I think, that only a small number of CO's MD-80s had this feature. Some European operators upgraded their MD-80s with new cones and replaced the old ones. SAS and Finnair come into my mind. Others left their older MD-80s with the old cone and received newer ones with the new one, like Alitalia.

From what I understand the gate agents didn’t notice much of a difference either.
