The Norwegian Air Shuttle Group and Lufthansa Technik have signed a contract extending an existing Total Engine Support contract. The agreement, signed on 17 September at the airline's headquarters in Oslo, covers all-inclusive services for the CFM56-7B engines powering the airline's current fleet of 115 Boeing 737-800 aircraft.

According to the contract, for the next five years Lufthansa Technik will cover all planned and unplanned shop visits at its highly dedicated CFM56 engine shop in Hamburg, Germany. The agreement also includes a far-reaching engine lease management. Lufthansa Technik will secure the leasing of spare engines for Norwegian to ensure the availability during peak overhaul periods. In addition, the contract includes the regular use of Lufthansa Technik's proprietary Cyclean Engine Wash and on-site services such as Airline Support Team Engines as well as the use of the portable aerotracer device.

Lufthansa Technik has been maintaining Norwegian's CFM56-7B engines since the fleet introduction of the Boeing 737-800 in 2008. Lufthansa Technik also supports the airline's 737-800 fleet with a range of other services, including extensive airframe maintenance.
