Hi there,

this one got me really puzzled. On the front page there is this nice VP-BGX photo which shows a B743 (below left). This is an ex-JA8189 ship (right).

Now I would appreciate if someone could explain to me: how come this B743 has wing fairings just like B744s have? Is this some kind of an intermediate variant? Is it known how many of such no-longer-300-not-yet-400 planes have been built?

I would appreciate any input.

Best regards
FAO

P.S.: Just in case: this is NOT a B744D.

Looking through the photos it seems to be after line number 703 where the new wing root fairing is introduced. I presume it was a design improvement.

Even the last built B742 which was line number 886 has the new style wing roots.

People often have the preconception that designs are stagnant between model derivatives. That is not true at all. Redesigning a faring sounds perfectly reasonable between derivatives.

Especially if you're going to certify the new design element (fairings in this case) for the next mark anyway.

Thank you all for the input. That helps me understand what I saw.

So, what was the line number of the first B744? Were there any B742/B743 built after B744 was introduced, or are these pictured airplanes actually an intermezzo for the yet-to-come new 400 series?

I assume that once B744 appeared there was no point continuing the old design across all variants, but perhaps some technical/logistic aspects could be an issue to switch at once...

Thank you again

There were indeed 742s and 743s produced after the first 744. If nothing else, you can tell by the line numbers. The first 744 was 696, while the last 742 was 886,

In the same way, there were 737 Jurassics produced after the introduction of the 737 Classic.Say that a custom had deliveries smeared out over 5-6 years. That customer would want to keep fleet commonality despite a new mark being introduced.
