Flying MC grounded in own Psychic phase, can then assault?

This was interesting. A Flying Hive Tyrant suffered a wound from Perils of the Warp on it's turn. This forces a grounding check at the end of the Psychic phase, which it failed. Thus now on the ground, can it assault that turn?
I assume it would be the same if an Interceptor weapon caused a wound when it came on the board from reserves.

Since it could be charged if this happened on the opponent's turn, I assume it could also charge if it was grounded on it's turn.

Nope. If it changes movement mode, it cannot Charge that same turn. It doesn't state how or when, just that turn. It could be due to Gets Hot!, and it would be Grounded till it can use a Movement Phase.
