Southwest Airlines Split-Scimitar Retrofits?

Thu Dec 06, 2018 10:14 pm

Hi all -

This is my first post to the forum. I live in an apartment about 2 miles east of KPHX and have been observing (ever so slowly) more of WN -700s built in the mid-2000s flying with split scimitar winglets. Is Southwest investing in these on their older fleet?

I haven't been able to confirm this on any publications or anywhere in the forum. However, a friend of a friend who pilots for WN said it's happening.

Any confirmation/discussion?

My understanding is that these devices generally return their investment inside of three years at current fuel prices, so if WN intends to keep the frame in service for >3y then it's a good investment. Moreover, if WN were to retire the frame, they could remove the devices and install them on another NG aircraft (they can be installed on all 737NG models except I don't think they were ever certified for the 736).

I recently flew onboard a WN 73G with split scimitar winglets, and it happened to be one of the ex-Chinese aircraft they've recently acquired. Perhaps they were delivered to WN that way?

The only link I found was for an order for a retrofit of 100% of the 738 with options for more:

It would be wise to convert the whole fleet IMHO.

AFAIK the N2**WN, N9**WN, and a few import B73Gs are getting the scimitar mod. The N7**SW and N4**WN have not received them yet and likely won't ever get them.

Most of the ETOPS B738s and a few of the earlier N86*** ones that originally had blended winglets have also received the scimitar mod.

Wouldn't surprise me if they are, but some airlines are better retrofitting it than others. UA and AS have been really on top of it, DL and WN are kind of hit or miss, while AA is the only one that has straight up refused.

I seen quite a few 737-700s with split scimitars whenever I'm spotting outside my house. Not sure how many have them now. The last time I seen a -700 with them equipped was way back in May of this year.

Keep in mind folks, I ball parked it with the 700s, there might be some I left out. I did all this from pictures and the top of my head. There’s a handful of the Chinese and a few Aeromexico birds that got the scimitar mod. I’d expect the N2** and N9** birds along with a few more ex airTran to get the mods. The N7** and N4** birds are all 1996-2005 vintage and might not get the mods. I’ve seen a few older UA 73NGs get the mod however. The 800 ETOPS and a handful of the N86** birds between 8600-8624 and 8624-8651 have the mod as well.

Additional 737-700 aircraft with split scimitars:

N232WN
N253WN
N267WN
N273WN
N285WN
N287WN
N291WN
N7732A
N7733B
N7737E
N7746C
N7862A
N7868K
N7869A

However, I have yet to find evidence of N958WN, N7865A, or N7866A receiving the mod.

On the 737-800 list, N8639B has split scimitars, but I do not believe N8607M, N8609A, N8638A, or N8648A do. N8605E was just at Indianapolis for month-long maintenance, so may have had the mod done while there, and N8606C is currently at KIND. Neither of these sported the split-scimitar winglets previously.
