Why No Winglets For The 737-400?
I have been wondering why Aviation Partners currently does not have any plans for winglets on the 737-400. They have already developed winglets for the 737-300, 737-700, and 737-800, with winglets for the 737-500 and 737-900 in the works. Why not the 737-400 though? The 737-400, while not very popular in the United States, was fairly popular outside the U.S., and in fact has sold in greater numbers than the 737-500 did globally. I don't see why they would choose to offer winglets for the 737-500 but not the 737-400, if more 737-400s have been produced. I could see why they wouldn't develop winglets for the 737-100, -200, and -600, as most airlines are retiring their 737-100s/200s, and the 737-600 was and still is a poor seller to begin with, and is not worth developing winglets for a small number of aircraft.

I'm pretty sure winglets are certified for the 734, but no airlines have chosen to fit their a/c with the winglets.

They should be indeed, as the 737-300, 737-400, and 737-500 all share the same wing. However, getting certification for them is much more complicated than just getting them to fit onto the wing.

And with US eventually going A319/20/21 , I wouldn't look for them to invest in winglets.Not sure on AS,but they already have 737NG's with winglets.

Does KLM plan to put winglets on their 737 fleet?

Correction: The two biggest operators (in the US) of the 737-400 are US Airways and Alaska Airlines

Only on the 800 and 900s. The 300s and 400s won't be around long enough to warrant the investment. Conversions should be completed after the winter season.

Ah...i was wondering whether they have to remove the lights (red and green lights that are placed at the end side of the wings)...Do they have to remove the lights and the installed the winglets?

The (new) 739ER has winglets and is being offered by Boeing as standard. The original 739 is no longer is production as I have just stated, the ER version is now being offered instead.

There are at least 2 735s flying for CO with winglets.

Likely a sponsor carrier is needed; i.e. a (sizeable) 734 operator willing to share in the development/cert costs.
I dumped at the gybe mark in strong winds when I looked up at a Porter Q400 on finals. Can't stop spotting.

The winglets have lights in them. They replaces the existing lights in the wingtip.

The 737-400 may not have enough margin left in the wing. They are available for the 737-300 and -500, which are both less highly loaded than the -400.

Maybe I am wrong, but I believe I read somewhere that the 734 did not achieve enough improvement in fuel consumption to warrant the expense to convert these aircraft.
