Narrative:

I was captain acting as support pilot. Runway was grooved and it was raining moderately to heavy. We touched down long but within touchdown zone. Aircraft hydroplaned, then entered area of rubber deposits on last 2000 ft of runway where it had nil braking. Aircraft ran off end of runway where it suffered no damage. Main cause of incident was hydroplaning despite grooved runway, plus rubber deposits at opposite end.
