After several engine problems, 29 Bombardier aircraft belonging to the Swiss Lufthansa subsidiary Swiss remain on the ground for review. Many flights had to be canceled, as the company announced on Tuesday. There is a noticeable restriction of flight operations.
The trigger was an incident on Tuesday morning: A Swiss machine had to land due to an irregularity in the engine on the way from London to Geneva unscheduled in Paris. The airline spoke of a "renewed incident with a Pratt & Whitney C Series / A220 engine". Since July 25, there have been "three cases of engine irregularities", said a Swiss spokesman.
In the evening, Swiss announced that the first aircraft were in "perfect condition" back in service. According to the current state of the air traffic on Thursday next run again largely normal.
Update 1/2: After a comprehensive engine inspection the first C Series has already returned to service in perfect condition. Based on the current planning the flight operations can be resumed on Thursday in a regular way.
- Swiss Intl Air Lines (@FlySWISS) October 15, 2019The aircraft come from the Canadian company Bombardier. Airbus took over after financial problems with Bombardier the majority of the shares in the aircraft program. That's why the machines now carry the Airbus A220 certification. At Swiss fly two variants, with 125 and 145 seats. Swiss introduced the C Series CS100 in July 2016 as the world's first airline.
"Swiss takes these incidents very seriously and works closely with the relevant authorities, Airbus Canada and the engine manufacturer (Pratt & Whitney)," said Swiss. "The safety of our customers and crews is our top priority." US engine manufacturer Pratt & Whitney advised airlines to investigate further. It is about the low-pressure compressor.
