If it's the same incident that I heard about, all four engines were ruined. Replace not repair. Anyone who used an air breathing engine down wind after the Mt. St Helens eruption was in the same position.

It can be a safety issue too. The ash is fine as talc. Heard an interview on NPR yesterday with a retired British Airways captain. Flying a route near Indonesia several decades ago in a 747. Dark night, no moon, flew into an ash cloud at 30 some thousand feet. All four engines quit - the crew finally got them restarted decending though 12,000 ft.

I doubt it's as much of a safety issue as a "what does it cost to replace all the engines and leading edges on all our planes after we run them through nature's great sandblaster" issue.

They'd just about be better off handing out a 645D to each passenger.
