Narrative:
Was approximately 53 mi south of cle. Akron approach cleared direct ritzs from present position, RNAV direct cle. PIC looking at chart sees/reads intersection and proceeded RNAV direct reads mistaking that intersection for ritzs. This situation could have been avoided by having a heading assigned with the clearance to the intersection or, not having closely named intxns within the same relative proximity of each other. Also the phonetic spelling would have helped had it been given with the clearance. Within the cleveland approach transitions there is ritz intersection, 170 degree, 25 NM from cle. Reads intersection, 210 degree, 45 NM from cle. Reels intersection, 260 degree, 58 NM from cle. This can tend to lead to confusion with amended root clrncs while airborne.

Title: HEADING TRACK DEVIATION OCCURS AS SMA PLT MININTERPS CLRNC ROUTE BY MISREADING INTERSECTION NAMES ON CHART. CLAIMS THAT THEY SOUND ALIKE.
Narrative: WAS APPROX 53 MI S OF CLE. AKRON APCH CLRED DIRECT RITZS FROM PRESENT POS, RNAV DIRECT CLE. PIC LOOKING AT CHART SEES/READS INTXN AND PROCEEDED RNAV DIRECT READS MISTAKING THAT INTXN FOR RITZS. THIS SITUATION COULD HAVE BEEN AVOIDED BY HAVING A HDG ASSIGNED WITH THE CLRNC TO THE INTXN OR, NOT HAVING CLOSELY NAMED INTXNS WITHIN THE SAME RELATIVE PROX OF EACH OTHER. ALSO THE PHONETIC SPELLING WOULD HAVE HELPED HAD IT BEEN GIVEN WITH THE CLRNC. WITHIN THE CLEVELAND APCH TRANSITIONS THERE IS RITZ INTXN, 170 DEG, 25 NM FROM CLE. READS INTXN, 210 DEG, 45 NM FROM CLE. REELS INTXN, 260 DEG, 58 NM FROM CLE. THIS CAN TEND TO LEAD TO CONFUSION WITH AMENDED ROOT CLRNCS WHILE AIRBORNE.
