Aerospace Engineering Solutions (AES), a UK and Ireland aerospace design and certification organisation, has been awarded an STC (Supplemental Type Certificate) by EASA (the European Union Aviation Safety Agency) for the introduction of a full economy passenger layout on Boeing 737NG aircraft types.
AES has developed this generic EASA STC (No. 10077620) for 189-seat cabin configurations, and it applies to the B737NG Family following the release of EASA Certification Memo CM-21.A-CS-001 Issue 02, which states that the installation/reconfiguration of aircraft cabins that involve 16G / 25.562 shall be considered as a Major STC change.
The STC has been established to add further variations under the agreement of EASA, providing an adaptable solution.
