Most probable:
Unstable approach due in part from lack of recency.
Gear was down.
CRC warnings were from flap overspeeds.
Improper go around. Selecting Flex/MCT instead of TOGA/GA or TOGA Tap. Recency issue again.
Gear selected up as aircraft was still pointing towards the runway.
Two impacts due to skip. TOGA finally selected or manual raising of the nose for go around.
Both engines fail on downwind due impact damage.
Its almost happened before.
