Norwich Airport are investing £7 million into the building of a new hangar and workshop facilities for KLM UK Engineering.
The hangar will be 54,000 sq ft and the workshop 15,500 sq ft. Both will be ready by August 2020.
"This will enable us to provide a more efficient service to our customers, allow us to maintain the larger next generation aircraft and provide extra capacity with a sixth bay," said Peter van der Horst, managing director at KLM UK Engineering.
KLM UK Engineering employs 390 staff at its Norwich headquarters. It also delivers aircraft engineering apprenticeships and training through its technical training college at the neighbouring International Aviation Academy Norwich.
"This deal underlines its long-term commitment to the region," said Norwich Airport managing director Richard Pace.
"(And it) is another significant milestone in the airport’s strategy of creating a global aviation centre of excellence."
