The SWISS Technical Division, with its 800 employees, is responsible for ensuring the technical safety of the fleet. The SWISS Technical Division is based at its main Swiss hub of Zurich Airport, plus Geneva Airport, and at various outstations around the world.
Safety is our top priority: every SWISS aircraft undergoes a rigorous technical inspection before every flight. In addition, comprehensive maintenance work is carried out at precise intervals. The SWISS Technical Division replaces more than 5,000 aircraft components each month.

The rubber tyres on the undercarriage are exposed to brief but very strong forces when manoeuvring on the runway and during take-off and landing. That is why the tyres of our long-haul aircraft are changed after about 250 flights (approximately every six months). This routine task is performed reliably by the specialists of the SWISS Technical Division.
When landing, the aircraft is brought to a stop by reversing the engine thrust and then applying the brakes on the main wheels at a speed of about 80 knots. During this manoeuvre, the carbon discs reach temperatures of up to 300 °C. The SWISS Technical Division replaces the 130 kg brakes before their power starts to diminish due to wear and tear. For the long-haul fleet, the brakes are changed every two to three years.

... and all other colleagues working in hangar maintenance!
An aircraft engine lasts for several years if properly serviced and maintained. With 13,640 horsepower (Airbus A321/CFM56-5B), it is 100 times more powerful than a car engine.
After about 25,000 flight hours (or eight years on average), 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 inside a new noise protection hangar at Zurich Airport. The innovative system operates around the clock and – thanks to extreme noise insulation – without disturbing local residents.

The on-board service is highly reliant on a well-functioning infrastructure inside the cabin. Before every flight, the SWISS Technical Division checks the kitchen and seats, the in-flight entertainment and air conditioning, and the lights and oxygen masks. If something is not right, it is corrected immediately.

The avionics compartment below the cockpit of a modern passenger plane houses the computers for system control and navigation. All data required for a safe flight is displayed on monitors in the cockpit. The SWISS Technical Division checks the entire electronics system before the pilots come aboard.
