KF Aerospace has successfully certified the first conversion of a Boeing 737-800 Combi. Transport Canada has issued the corresponding Supplemental Type Certificate (STC #SA25-72), allowing the company to put the aircraft into operation. The newly certified 737-800 Combi features a special multi-role configuration that includes a forward cargo compartment with five pallet positions and a passenger area for 90 people in the rear. With this configuration, the aircraft is the first of its kind worldwide, as there are currently no comparable Combi models in the USA, Europe, or other international markets. The first aircraft was delivered to Air Inuit in October 2025 and is part of the airline’s fleet modernization.
Expanded Operational Capabilities Through New Certification
The STC certification of the 737-800 Combi expands the operational capabilities of the aircraft and builds on the proven functionality and reliability of the AEI 737-800SF with a large cargo door. This certification is the result of a long-standing collaboration between KF Aerospace and Aeronautical Engineers, Inc. (AEI). Robert T. Convey, Senior Vice President at AEI, emphasizes: “The achievement of the 737-800 Combi highlights the strength of the partnership that KF and AEI have maintained over three decades.”
The implementation of the program required a comprehensive redesign of the aircraft’s interior and systems to meet stringent certification requirements. KF Aerospace developed fire detection, Halon-based fire suppression, and advanced smoke containment systems for the forward cargo compartment and adapted existing cargo-specific detection systems to meet the needs of the Combi configuration. This led to the creation of hundreds of new parts and customized solutions to realize this technically complex conversion program.
Gregg Evjen, President of KF Aerospace, highlights the achievements of the entire team: “This project reflects the creativity, commitment, and deep technical expertise of our entire workforce.” The conversion showcases the advanced capabilities of KF’s in-house engineers and the crucial role of the manufacturing, installation, and testing teams throughout the conversion process.
The newly certified 737-800 Combi directly meets customer demands for a high-volume, mixed-use aircraft that can accommodate both cargo and passengers. Furthermore, the project demonstrates KF Aerospace’s ability to overcome regulatory and engineering challenges that have historically limited the development of Combi aircraft worldwide.
This development underscores KF Aerospace’s role in innovative conversions, advanced engineering, and the development of customized STCs. The company thus demonstrates its ongoing commitment to delivering industry-leading solutions through close collaboration among engineering, certification, production, and partner teams.
