L-1011 TriStar Model Designations . . .

Sat Mar 20, 2004 2:14 am

I have a simple question. Why are there so many different ways to refer to a model designation of an L-1011 TriStar. For example, I have seen the -1 referred to as an L-1011-1 or as L-1011-385-1 or other numbers in place of the "385" like L-1011-###-1. What is the purpose of this? What does the "385" mean? Can anyone help me?

Customer number? Engine type? Toilet config?

ahhh, lockheed numbers... this should be fun:

Actually its more alike: L-1011-385-1-14 Tristar 100/150 or L1011-385-3 Tristar 500.

now if you want the FULL thing: L-1011-385-1-193A for an original Eastern Tristar 1, L1011-385-1-14-193E for an Air Canada Tristar 100, any airlines that bought -500s got a second customer code for those. Why 193? dont ask me...

ok so lets break this down L(Lockheed) 1011 (model) 385 (something to do with the design number) 1(subtype, 1 for standard body, 3 for the 500) 14 (version, not on Tristar 1 or 500, 11=Tristar 50, 14=100/150, 15=200) 193A (customer code, 193A=Eastern, 193B=Eastern 193C= British Airways, 193E=Air Canada, 193K=Court Line, 193R=LTU, etc theres probably a full list online somewhere, i dont have time to look it up now).

Just to throw one more wrench into this, 3 designations that never got built:

L1011-385-8M, DC-10-30 competitor, never got built, pity...
L1011-385-4 Tristar 600, Twin Engine
L1011-385-9C, sometimes called L1011-700, L1011 for mid-80s introduction with FBW, GE/RR/PW engine options, winglets on some drawings... Lockheed MD-11 competitor. design never progressed beyond drawing board, killed with L1011 program in early 80s.

Thankfully only the Tristar is this confusing, the L-188 used the Older letter (A or C) subtype system used by the Constellation line and previous designs.

I'll give you some info from the L-1011 Airliner Tech Series book. It may not be complete, but here goes:

L-1011-1: basic model, with RB 211-22B, max gross weight was 430,000 lbs
L-1011-100: max gross weight 466,000 lbs, allowed center section fuel tanks
L-1011-200: same as -100, but had RB 211-524 engines
L-1011-500: long range version subtracted 13' of fuselage, added 9' to wingspan

With regards to the -385, I'll quote directly from the book: "In addition to the dash numbers, you may see numbers such as L-1011-385-1, which refer to the Federal Aviation Administration (FAA) certification designation for a particular model L-1011. These numbers include 385-1, 385-1-14, 385-1-15, and 385-3".

Hope this helps.

Thank you so much NorthStarDC4M and Tom in NO. That info was really quite helpful. It is very confusing. I just never got all the numbers. All I know is, Lockheed had the L-1011-1/-50/-150/-200/-250/-500. So all of those other numbers had me thinking, "What's going on here"? LOL. Thanks a lot.

actually Lockheed never built a -250, the -250s were converted by Delta.

and you're welcome  Smile

The break down is as follows:

L-1011-385-1-14 193A

385 is the type certification designation; with the configuration subpart being the 1 (body; 3 being the "-500"); and 14 (11/14/15) being post configuration ammendments from the straight -1. The customer designation follows as a suffix. In type certification and company records; the title "TriStar 100 or TriStar 500" is never used, nor are the customer codes.

The Delta -250 conversion remains as its original certification; L-1011-385-1 XXXX.

The original customer codes are as follows:
193A - Eastern (i.e. L-1011-385-1 193A)
193B - Trans World
193C - Delta Air Lines
193E - Air Canada
193F - Trans Carib (ntu)
193G - BWIA (385-3)
193H - Air Canada (385-3) (i.e. L-1011-385-3 193H)
193J - LTU (385-3)
193K - Court Line
193L - PSA
193M - Haas Turner (ntu)
193N - British Airways
193P - All Nippon
193R - LTU
193S - Saudia
193T - Cathay Pacific
193U - Gulf Air
193V - British Airways (385-3)
193W - Delta Air Lines (395-3)
193Y - Pan Am (385-3)
293A - ALIA
293B - TAP Air Portugal
293C - British Airtours
293F - Air Lanka

What does the "385" mean?

IIRC, the 385 meant 385,000 lbs. MGTOW for the original design.
This plane is built to withstand anything... except a bad pilot.
