No: it's not just "might need to run fsck". It's data corruption of unknown parts of the filesystem. Not on a pair of crashes: a single crash is enough. If the disk was quiescent the damage might be negligible or non-existant, but in the normal case, I'd be looking at recovery of newest writes and restore the rest from backups.
