I'd be very wary of making an approach at ~50kt following an engine failure. You might find - too late - that it takes a fair bit more than 50' of height to build up enough speed to make a flare viable. Particularly if the a/c is near or at MAUW.
I know a guy who got behind the drag curve in a 207 following an engine failure. The impact marks showed the wingtips hit the ground almost at the same point as the fuselage impact point. (They all died on impact.)
