United Launches Split-Scimitar Winglets For 737-900ER

Aviation Partners Boeing has launched the split-scimitar winglet program for the Boeing 737-900ER with an order from United Airlines. The carrier had already launched a similar program in January for its 737-800s, with FAA approval for a supplemental type certificate (STC) expected in October. The 900ER STC should be approved next February. The split-scimitar winglet modifies the existing blended winglet with a new cap section, and adds a ventral strake. Aviation Partners Boeing estimates that a 900ER equipped with the winglets will save around 57,000 gallons of fuel over the course of a year. The company is looking to extend its STCs to cover other 737 Next-Generation aircraft such as the BBJ1 and 737-700.
