Winglets on new Alaska 737-900s

Wed Oct 19, 2016 2:10 am



As Alaska unveiled its latest 737-990/ER (N265AK) I couldn't help but notice it was equipped with standard scimitar winglets, while the vast majority of the 737NG fleet (aside from the oldest 739s) are equipped with the split scimitar winglet. The planes with standard winglets seem to only be on -900 and -900ERs, but some of those have split scimitars and there doesn't seem to be a pattern as to which planes get the split scimitars.
Why doesn't AS have split scimitars on all possible aircraft, especially new ones?

My guess is that the split scimitars get added on a secondary check later on so they probably fly their first couple hundred hours without them.

For those that existed before the split scimitar was an option, they probably get added in C check or as part of a secondary mod (all depends on what the fleet utilization is)

It has standard winglets from the manufacturer and will be retrofitted with the split scimitar winglets at a later date as those are essentially an aftermarket job.

All new 900ER's from the factory come delivered with standard blended winglets typically matching the color of livery. Shortly after delivery and almost always before it makes it's first revenue flight it is modified where the blended winglets are removed and split scimitar winglets are installed; they match the livery when installed. Boeing does not offer the split scimitar as an option.

All of the 800's are modified with split scimitars.

9 of the 12 900's (delivered early 2000's) have winglets, most are blended with some being split scimitar but the remaining blended winglets are being replaced with splits. The first three 900's (N302AS, N303AS, and N305AS) do not have any winglets.

All 700's have blended winglets.

With regards to the AS fleet of 737-900ER's, how many are ETOPS vs how many are not? I see according to their webpage they currently have a fleet of 51 total 737-900ER's, ith that being 53 by years end.

I was pretty sure that when AS took delivery of their first 900's, that none of them were coming ETOPS & the 800 was going to be the ETOPS certified model.

Then AS started taking the 737-900ER which has the legs for Hawaii came on line it was still only the 800's flying to Hawaii. 900ER's have subbed before, Now when AS is taking delivery of each new 737-900ER, are they all coming ETOPS or is there a mixture of both certified & non-certified?

Thanks for that information. For future 900ER deliveries will they all come ETOPS from now on?

I know the 900's are not ETOPS with their limited range.

I'd also be curious if AS is taking on more 900 / 900ER / 800 aircraft with their upcoming deliveries from Boeing? I see more flights being operated by 900s & 900ER's.

I dumped at the gybe mark in strong winds when I looked up at a Porter Q400 on finals. Can't stop spotting.

All the N2xxAK registered planes that began with the first delivery in April of this year are non-ETOPS.

Is the winglet a standard 73G fitting now? Wouldn't it make more sense to order them without winglets and then add the scimitars after delivery rather than have the winglets only to remove them and re-fit split scimitars?

Or is AS going for the winglet mod in which the top of the winglet is replaced with the scimitar tip and the additional lower wing-like element is added?

The winglet is standard on the -900ER.

They come with the standard winglets and are replaced by aviation partners with the ss via STC.

I don't think boeing sells 737's without winglets anymore but could be wrong.

Correct. All deliveries between now and when the Max arrives will be non-ETOPS.
