737–800 Winglet Integration

A joint venture called Aviation Partners Boeing successfully integrated winglets into the Next-Generation 737–800 by retaining performance improvements with minimal weight penalty on the existing 737 wing design. Program challenges included developing both retrofit and production configurations using a common winglet design, causing minimal impact on all customers, and causing minimal disruption to the 737 production process. Winglet benefits along with improved performance include reduced engine wear and enhanced visual appeal.
