Incident: Ryanair B738 near Tenerife on Oct 11th 2021, engine trouble after flying through volcanic ashes
Apparently both engines had ingested ashes of the volcano Cumbre Vieja on La Palma Island about 75nm northwest of Tenerife South Airport.

It is doubtful that they can be used again.
The aircraft is still at Tenerife South airport.
