I have air layered a few cherries successfully. I've seen others instruct 
on the subject, but I'm not an expert at it. Now that you know my 
qualifications.... :-).

Cut away only about 1/4 inch. The roots develop at the edge of the bark 
near the upper cut edge. Cut the bark only do not remove the xylem, only bark 
and cambium. Also apply a small amount of IBA rooting hormone to the bark 
maybe an area of 1/2 inch above the cut. 

I've heard others say simply score the bark all around the limb and apply 
the IBA around the cut. 

Just checked a reference book I have, "Plant Propagation in Pictures" by 
Montague Free, 1957. In it he reports about an average of 50% success on 
Malus. Some Malus species were more successful than others. 

Do try it again next spring after the leaves have developed.
