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.

Quoting FlyboyOz (Reply 8): 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 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.
