I was attacking and the MCC was halfway across the map. I flew my dropship up on top of my MCC to set a spawn point and let some one else pilot it. I ran to the tip and jumped off, activated inertia dampener immediately and hit the overpass by objective C, and reactivated the inertia dampener again. After landing, I still had the inertia dampener animation around my character while walking, running, and shooting.

Steps to reproduce:
Attacking on skirmish.

1) Wait untill the MCC is flying over objective C.
2) Call in a dropship and get enough altitude to reach the dropship.
3) Fly on top of the MCC and get off the dropship unto the MCC.
4) Run/walk to the tip of the MCC where the right antenna is pointing horizontally from the tip.
5) Jump off in a way so that you will hit something while you're falling and activate inertia dampener.
6) After colliding with the building behind objective C while still falling, quickly activate inertia dampener.

The animation of the inertia dampener should not have canceled after hitting the ground.

also, has any one else experience the inertial dampener effect to jumping from extreme heights where the VFX starts off with you free falling then turns you around so that you can only look at the horizon and you land standing up. I have had this happen only when jumping off the towers on the west and eastern edges of the map. One time it even got me killed because I couldn't see what was below me.
