There is no sign of FOD though. the bending of the blades is almost same as your first image. I suspect that the abradable coating in rotor path came chipped off (as a large piece, but it cannot be confirmed because the rubbed area doesn't look so) because of any ovality in casing and it might have struck in between blades and rotor path. Total 5 blades got bended. first in the five got more damage and the following ones got less bend. | |

| Nov 28, 2016 at 16:21 | comment | added | DeltaLima♦ | Is it specifically the leading edge of the tip of the blade that is bend forward? | |
