Blended Winglet configuration. FAA granted supplemental type certification (STC) for the Split Scimitar Winglet (SSW) retrofit on the 737-800 and BBJ2 on February 6, 2014, for 737-900ER on August 27, 2014, for 3 additional 737-800 wing configuration on October 2, 2014, and for all models of the 737-700 including the Boeing Business Jet on April 21, 2015.

APB's Split
Scimitar Winglet retrofit program consists of retrofitting 737NG's winglets by replacing the aluminum winglet tip cap with a new aerodynamically shaped "Scimitar" winglet tip cap and by adding a new Scimitar tipped ventral strake. This modification demonstrated approximately 2% drag
