SR Technics , based at Zurich Airport in Kloten ( Switzerland ), is one of the world's largest, independent providers of technical services in civil aviation. The company offers maintenance, repair and overhaul (MRO) services for aircraft, components and engines.

SR Technics has been owned by the HNA Group (80%) and Mubadala Development Company (20%) since July 15, 2016 .


In the 1970s, the engines of the DC-9-32 of East African Airways came to Zurich for revision in an under-wing container of the VC-10 .

SR Technics was a subsidiary of SAirGroup . With a turnover of more than CHF 1.4 billion, it was one of the world's leading companies in the areas of maintenance for aircraft , engines and components. Over 50 airlines worldwide had their fleet or parts of it serviced by SR Technics.

Until the end of 1994, SR Technics was the technical department of Swissair founded in 1931 (Department 4). In 1995 the technical department became a profit center under the name "Swissair technical services".

In 1997, the Swissair group took the step towards the holding structure and changed the name to SAirGroup. This holding company consisted of the corporate divisions SAirLines, SAirServices, SAirLogistics and SAirRelations.

As a result of this change, Swissair technical services acquired legal personality as SR Technics in the SAirServices division on January 1, 1997.

The advancing internationalization and globalization made it necessary to adapt the structures of SR Technics to the new circumstances. The SR Technics Group was founded in 2000, in which SR Technics was henceforth integrated as SR Technics Switzerland. Shannon Aerospace, Temro, SR Technics France and SR Technics America also belonged to this group. SR Technics America was in turn divided into SR Technics Palmdale, WASI, Flight Technics, Willis Lease Finance and Pacific Gas Turbine.

After the collapse of SAirGroup at the end of 2001 ( grounding ), SR Technics was sold to various investors in December 2002 , the establishment of a holding structure began, and SR Technics again became SR Technics Switzerland. The main shareholders were 3i plc and Star Capital . The companies Shannon Aerospace, Temro, SR Technics France and SR Technics America, which belong to SR Technics, were also sold, as were all other still healthy parts of the SAirGroup.

In 2004, FLS Industries sold its aircraft maintenance companies FLS Aerospace Ireland and FLS Aerospace UK to the SR Technics Group. At the beginning of 2005 these were then transformed into SR Technics Ireland Ltd. and SR Technics UK Ltd. renamed.

On September 7, 2006, Group management announced that SR Technics was being sold to a consortium based in the United Arab Emirates with long-term strategic interests in the aviation industry. 92 percent of the shares went to the three companies Mubadala Development , Istithmar and Dubai Aerospace Enterprise (DAE), which are owned by the ruling families of Abu Dhabi and Dubai , for 1.6 billion Swiss francs . The remaining 8 percent of the share capital remained in the possession of the management.

At the beginning of February 2009, the group management announced the closure of the Dublin site, which had around 1,100 employees , as extensive customer orders had been lost at the Dublin site and the prospect of new orders was not considered possible in the medium term due to the high costs of the site. As part of the global aviation crisis, SR Technics also announced job cuts at the Zurich location in June 2009, which affected around 300 employees.

In November, SR Technics concluded a contract extension and extension with the low-cost airline easyJet . The contract has a term of eleven years and a sales volume of 1.6 billion US dollars. SR Technics provides line maintenance and heavy maintenance services as well as component maintenance and the provision of spare parts. At the same time it was decided to open a new maintenance location on the island of Malta, in which aircraft the size of an Airbus A320 or a Boeing 737 can be serviced. The execution of IL checks on aircraft of the easyJet fleet in an existing hangar was already started there in 2010.

In January 2010, the group management announced the closure of the components business at the London-Stansted location. This included around 340 jobs. Most of the activities there were then to be carried out at the headquarters at Zurich Airport.

On February 1, 2010, the previous CFO, James Stewart, also took over the position of CEO, succeeding Bernd Kessler, who had resigned with the mutual consent of the Board of Directors.

In April 2011 SR Technics announced the opening of the VIP Completion Center, in which luxury facilities will be installed according to customer requirements. Seven months later, the Mubadala Aerospace MRO network was founded, which consists of SR Technics and Abu Dhabi Aircraft Technologies (ADAT). Mubadala Development Company became the sole owner of SR Technics.

On September 29, 2011, the group management announced that over 200 jobs would be cut at the Zurich location, which corresponds to around 7 percent of the total workforce. The reason given was that the franc was too high.

Since July 2012, all Finnair engines and components have been serviced by SR Technics in Zurich. Finnair justified the decision by saying that it wanted to concentrate on its core business. The cooperation would also improve the cost efficiency of engine and component maintenance while maintaining the same quality.

In 2013, SR Technics expanded the strategic partnership with Etihad with an extended ten-year contract for Integrated Component Services (ICS).

In 2014 a new repair shop for components was opened in Malaysia, whereupon a twelve-year contract for MRO was signed with Philippine Airlines in 2017.

In 2015 Jeremy Remacha took over the management. In 2016, 80 percent of the shares were transferred from the Mubadala Development Company to the HNA Group. As part of this change of ownership, CEO Remacha was replaced by Frank Walschot at the beginning of April 2018. In September 2019, Jean-Marc Lenz took over the management.
