The procedure is probably only for the time they do maint on the VOR LT. They had a VOR-DME approach before, but this NDB was issued 20.October2000. There is no step down, when on final course you have to leave 3300´for the min of 2300´. The hill comes later, so if you stay visual on the PAPI-path and join the centerline as soon as you reach the min, your path almost hits that hill (at least in my opinion).
