Swiss grounds CSeries/A220 fleet for immediate engine inspections
15 October 2019

Swiss International Air Lines decided to ground their fleet of Bombardier CSeries/Airbus A220 fleet for immediate engine inspections following a new incident.

The first inflight shutdown occurred on July 25, 2019 and the second occurred on September 16, 2019. In both cases, the aircraft involved was a Swiss International Air Lines Airbus A220-300 with Pratt & Whitney PW1524G-3 engines. These inflight shutdowns were due to failure of the low-pressure compressor (LPC) stage 1 rotor, which resulted in the rotor disk releasing from the LPC case and damaging the engine.

A third recent incident led Swiss to decide to ground the fleet on October 15, 2019. The aircraft will “undergo an extensive examination from midday”, according to the airline.

Details of the third incident are unconfirmed at this time. It appears the aircraft involved was HB-JCC, an A220-300 that diverted to Paris-CDG Airport during flight LX359 from London to Geneva.

 

The grounding follows an FAA airworthiness directive that was issued on September 26, which requested initial and repetitive inspections of certain Pratt & Whitney PW1500G series engines.
