Aeronautical Engineers, Inc. (AEI) has received approval from the Federal Aviation Administration (FAA), which allows it to use Split Scimitar winglets in its B737-800s aircraft conversions.

AEI said it is the first supplemental type certificate (STC) conversion provider to achieve the approval. It added that it will not charge an additional fee to convert aircraft with Split Scimitar winglets.

"Currently, there are approximately 853 B737-800 aircraft retrofitted with the winglets, so this approval now substantially increases the candidate aircraft available for passenger-to-freighter conversion by AEI," the company said.

Robert T. Convey, AEI senior vice president of sales and marketing, added: “AEI is once again leading the industry by providing advancements that matter to operators and aircraft owners.”

The AEI converted B737-800SF freighter offers a main deck payload of up to 23.9 tonnes and incorporates eleven full height 88” x 125” container positions.
