TEI is a joint-venture company established in 1985 with the partnership agreement signed by Turkish partners (53.78%) and General Electric (USA) (46.22%). TEI’s Turkish partners are TUSAS-Turkish Aerospace Industries INC., Turkish Armed Forces Foundation and Turkish Aeronautical Association.

Established with the aim of building assembly and testing capability of F110 engines of F16 aircrafts which is a national project; transfer of aircraft engine manufacturing technology; gaining the capability of manufacturing aircraft engine parts and building a permanent aircraft engine industry in the country, TEI realized the first shipment of engine and engine parts in 1987 and then proceeded to growth process as of 1989.

Determining its vision as “being the main manufacturer of a worldwide, high quality and competitive aircraft engine”, TEI’s mission is “building a permanent aircraft engine industry in the country providing products and services which will develop technological basis of aviation and space industry”.

TEI has proved itself in aviation with both national and international projects successfully engineered for aircraft and helicopter engines in military and commercial fields from its first years on. TEI is taking firm steps forward to be the main manufacturer of aircraft engines with its constantly developed infrastructure, manufacturing, engine assembly, testing, maintenance, repairing, revision and design capabilities; its service capacity exceeding customer expectations and its quality applications.

TEI’s main fields of activity are Parts and Module Production, Engine Assembly and Test,Maintenance, Repair and Overhaul, Services, Engine Design and Product Development.

In the field of engine assembly and testing, TEI is making use of its high-tech capabilities in the projects such as assembly and testing of F110 engines for F-16 aircrafts; assembly and testing of Makila 1A1 engines for Cougar helicopters and Depot Level Maintenance of TF33 engines of NATO AWACS aircrafts. Starting from 2008, Service Life Extension Program (SLEP) and Engine Structural Integrity Program (ENSIP) for F110-GE-100 and F110-GE-129 engines have been implemented and maintenance and overhaul processes for CT7-9C engines of CN-235 CASA aircrafts are carried out.

Mentioned as “Center of Excellence” in manufacturing parts and the sole source for most of the manufactured engine parts, today TEI’s manufacturing parts approach the number of 650 for 37 different engine programs in military and commercial arena.

Competing with leading manufacturers in the world in engine part manufacturing, TEI gains new technological capabilities in order to be an engine part manufacturer completely.  In this direction, TEI realized another important project by signing an agreement in 2009 with its partner GE Company to adopt blisk-spool manufacturing technology. Mentioned project will be realized by using the latest manufacturing technologies and TEI will be one of the few companies in this area. New generation blisk and spools manufactured making use of advanced manufacturing techniques and high technology decrease the amount of weight and emission prominently in the engines and provide fuel saving and superior performance. Together with implementing this project, starting from 2011, a capability of manufacturing key parts of an engine, ranging from fan to compressor and from turbine to exhaust will be obtained.

Technical support services furnished by TEI for high tech aircraft and helicopter engines in the country to meet customer expectations are becoming prevalent more and more for commercial engines in the regional countries that passing our borders.

Participating in international aviation projects in the field of design and carrying on its future investments, TEI has projects such as TP400-D6 engine project of A400M aircraft; F136 engine project of Joint Strike Fighter (JSF), authentic turboprop engine project (TEI-TP-1X)  for Unmanned Air Vehicles. TEI is continuing its activities of ATAK and Turkish Armed Forces Helicopter Engine projects.

As of today, realizing engineering and manufacturing projects with the title of Global Engineering Center, TEI is shaping its future in the fields of design and engineering in addition to manufacturing in line with its vision.

TUSAŞ and TEI signed a Collaboration Agreement in 2007 to start national platform- national engine model ensuring maximum national benefits in the field of aviation; and in 2008, authentic TEI-TP-1X turboprop engine developed by TEI was flight tested successfully. The mentioned engine was designed by TEI’s engineers by using high-tech methods and manufactured by using the TEI manufacturing technology and also other technological means in the country.

Besides that, Turkish Technology Center established in Tubitak MAM Technology Free Zone with the agreement signed between TEI and GE Aviation in 2007, and whose permanent building was opened in 2009 serves to TEI’s aim of being the main manufacturer of aircraft engines. In the center, technology development works including manufacturing and quality processes are carried out besides design operations for commercial and military engine programs of GE Aviation particularly F136 .

Achievements in above mentioned activities result in TEI’s turnover. TEI’s total sales figure is approximately 300 million USD, more than half of which comes from export.

Taking place in a difficult field like the aviation sector requiring high technology, TEI ranks 200th in sales from manufacturing and 59th in export out of 500  big industrial enterprise according to quest of “500 Major Industrial Enterprise of Turkey” done by Istanbul Chamber of Industry.

TEI gave acceleration to its activities in supply industry to strengthen technological infrastructure of our country; to extend the supply industry network and to create new employment opportunities by getting more employment share from international aviation market. Increasing part manufacturing year by year, TEI brings in new manufacturing technologies not available in the country to product range on one side, and opens its scale of manufacturing to the supply industry firms as much as possible on the other side. TEI, parallel to its growth targets, fosters supply industry firms and improves their manufacturing capacities and quality infrastructures.         

TEI, the owner of the 1984 TÜSİAD-Kalder Quality Award, encourages creativity, innovation, continuous development and has made innovation an integral part of its culture with the use of 6 sigma methodology.

TEI owns well-trained, qualified and experienced 1100 employees today. TEI provides improvement opportunities to its employees according to their skills in all fields of activity  together with its civilized human resources applications and learning organization structure from past to present.

Giving particular importance to quality and customer satisfaction and minding team work and constant development, TEI became a worldwide model establishment in the issues such as school-industry cooperation, environment, employee health and safety with the sense of responsibility to the public in which it takes place.
