If both props damaged this will mean 2 engine changes and gearbox's as well as all the blades,nosegear and doors,and any structural damage, this aircraft will be out of service for a long time, and the cost will be massive. For a airline that is cash poor this might be a very big dent in there finances......hard to source landing gears and engines for Atr, and this model has very different blades than a standard 72-200. Due to the larger rated engines on this model the blades are also different. This makes it even harder to source spares.
