I spent some time maintaining these simple and sturdy aircraft in Africa and quite enjoyed the experience. A great bush operations aeroplane (as long as weight and balance loading limits were obeyed). Regarding forced landings, this Wiki excerpt addresses the issue:
https://en.wikipedia.org/wiki/Antonov_An-2
"If the engine quits in instrument conditions or at night, the pilot should pull the control column full aft and keep the wings level. The leading-edge slats will snap out at about 64 km/h (40 mph) and when the airplane slows to a forward speed of about 40 km/h (25 mph), the airplane will sink at about a parachute descent rate until the aircraft hits the ground."
