Turkish Aerospace (TUSAŞ) has been awarded a contract by Boeing for manufacturing and supplying Fan Cowls for Boeing 737, the legendary single aisle aircraft family. Turkish Aerospace will be responsible for 50% of the monthly 737 Fan Cowl requirements starting in 2025.

The agreement between Boeing and TUSAŞ expands the portfolio of Boeing Commercial Airplane products manufactured by TUSAŞ. The two companies’ close industrial collaboration supports the 737 program’s performance and affordability while furthering the longstanding relationship between Boeing and Turkey’s aerospace industry.

Fan cowl doors provide an aerodynamic surface over the fan case of the engine between the inlet and the thrust reverser and protect engine mounted components and accessories. There are two fan cowl doors (left and right) around each engine that can be opened to provide access for service and maintenance of the engine components and accessories on the fan case of the engine. 

Prof. Temel KOTİL, President & CEO, Turkish Aerospace, evaluated about the agreement and said, “Our company continues to be among the manufacturers that have proven in the field of aerostructure with its half a century of experience. In this context, while we continue to produce national projects in the field of aviation industry in our country, We also carry out high-quality critical productions for the world's leading aerial platform manufacturers. We are delighted for the fan cowl production for BOEING as part of the agreement. We bring a new ability to our company. I congratulate all my colleagues and BOEING authorities who contributed to this cooperation.”

Aysem SARGIN, Managing Director, Boeing Turkey, said, “Turkey is one of Boeing’s strategic growth countries, and we see tremendous potential for the country to contribute to the global aerospace industry as an industrial and technology partner. With the launch of Boeing Turkey National Aerospace Industry (NAI) by Boeing and Turkey several years ago, Boeing has expanded its investments, footprint and supply chain in Turkey. The award of the 737 Fan Cowl work package to TUSAŞ is a reflection of our continued commitment to Turkey and the wo rld-class capability of our industrial partners in Turkey.”

Fan cowls will be manufactured at the state-of-the-art TUSAŞ premises in Ankara-Turkey, where the Company is already contracted from Boeing to manufacture the Boeing 787 Dreamliner elevator, cargo barrier, horizontal leading edge, and 737 elevator, along with the deliveries of thousands of parts/components that are flying in Boeing airplanes for years.
