How Engineers Replace a 2.5-tonne Aircraft Engine


The team spirit in our international team is a motivating force – and the key to our success.An aircraft engine lasts for several years if properly serviced and maintained. With 13,640 horsepower (Airbus A321), it is 100 times more powerful than a car engine.

With reliable servicing, an aircraft engine will run for several years – and produces 13,640 hp (Airbus A321/CFM56-5B), which is about 100 times more than the average car.

The engines are serviced for the first time after about 25,000 flying hours, which is an average of eight years. The SWISS Technical Division overhauls the engines for the first time, each one weighing more than 2.5 tonnes.


Since 2014, the SWISS Technical Division has been testing aircraft engines at full thrust in a new soundproof hangar This innovative system operates around the clock – without disturbing the neighbours, thanks to the very high level of soundproofing.
