Swiss (LX, Zurich) has grounded the entire fleet of its A220s after one of the carrier's A220-300s, HB-JCC (msn 55012), experienced mid-flight engine problems on the morning of October 15 and had to divert to Paris CDG.
The carrier confirmed to aeroTELEGRAPH that all A220s will undergo "comprehensive inspections" prior to returning to service.
"The current technical review of several aircraft leads to a noticeable restriction of our flight operations, as many flights have to be cancelled," Swiss said in a notice posted on its website, without going into detail.
The October 15 incident is reportedly the third inflight shutdown of an engine on an A220 within the last three months.
According to Flightradar24 ADS-B data, all outbound flights of Swiss' A220s from Zurich and Geneva are currently cancelled. The airline continues to operate inbound flights.
With nine A220-100s and twenty -300s, Swiss is the world's largest operator of A220 Family jets. The aircraft form the backbone of its short- and medium-haul fleet, which also includes three A319-100s, nineteen A320-200s, six A321-100s, and three -200s. It also wet-leases ten E190s from Helvetic Airways.
airBaltic (BT, Riga), which is another major operator of the A220s with twenty -300s in its fleet, has not grounded its aircraft so far.
