Narrative:
After receiving an air navigation chart change to all the stars into memphis, I was flying into memphis. The middy 7 STAR had many significant route changes leading to gilmore and had studied these changes however because of a small change a bowen intersection and the many major route changes that I had studied I managed to miss the small change on the STAR at bowen. After flying the same STAR for many yrs I saw what I expected to see at bowen rather than what was actually on the paper. My suggestion to help prevent his oversight from happening with a new navigation chart change would be for chart manufacturer to be more specific about each change to a new plate. On this STAR chart only mentions all the changes collectively as the reason for the change; 'route changes.'

THE MIDDY 7 STAR HAD MANY SIGNIFICANT RTE CHANGES LEADING TO GILMORE AND HAD STUDIED THESE CHANGES HOWEVER BECAUSE OF A SMALL CHANGE A BOWEN INTXN AND THE MANY MAJOR RTE CHANGES THAT I HAD STUDIED I MANAGED TO MISS THE SMALL CHANGE ON THE STAR AT BOWEN. AFTER FLYING THE SAME STAR FOR MANY YRS I SAW WHAT I EXPECTED TO SEE AT BOWEN RATHER THAN WHAT WAS ACTUALLY ON THE PAPER. MY SUGGESTION TO HELP PREVENT HIS OVERSIGHT FROM HAPPENING WITH A NEW NAV CHART CHANGE WOULD BE FOR CHART MANUFACTURER TO BE MORE SPECIFIC ABOUT EACH CHANGE TO A NEW PLATE. ON THIS STAR CHART ONLY MENTIONS ALL THE CHANGES COLLECTIVELY AS THE REASON FOR THE CHANGE; 'RTE CHANGES.'
