Not withstanding the (lack of) sophistication of the A109S autopilot. Presumably it's sophisticated enough to enable the aircraft to be on the localizer and aligned with the runway center line. And in foggy conditions you stay on that localizer until DH, and at DH (with the required visibility) you continue down and land on the runway center line. And then ground taxi all the way to the dispersal point. 'Aint no way that helicopter was aligned with the runway center line when it met its demise.
And besides, there is absolutely no place for leveling off once established on an ILS approach prior to touchdown. The helicopter should be like a ping pong ball bouncing off a table at DH and carry out the missed approach if you don't have the required visibility (which is always to immediately add power at DH and climb). If you do have the required visibility at DH you continue the approach angle and alignment whilst slowing down until touch down. Either way, you never level off whilst in flight.
