A FLT OF 5 NORTH AMERICAN SNJ-2 ACFT WERE ON A FLT FROM LONG BEACH TO FRESNO, CA. BY PRIOR ARRANGEMENT, THE LEAD PLT IN N61563 WAS TO HANDLE THE RADIO COMMUNICATION WITH ATC FACILITIES. DURING ARRIVAL AT FRESNO, THE LOCAL CONTROLLER INQUIRED WHETHER THE GROUP DESIRED TO BE HANDLED AS A FLT. THE LEADER RESPONDED THAT THE ACFT 'WILL LAND INDIVIDUALLY.' THEREAFTER #1 RECEIVED CLEARANCE TO LAND ON RWY 29R. DURING THE LANDING, THE #1 PLT TURNED OFF ON HI SPEED TAXIWAY 'M', BUT WAS INSTRUCTED TO HOLD SHORT OF RWY 29L. HE ACKNOWLEDGED & COMPLIED WITH THE INSTRUCTION. THE #2 PLT IN N60645 ALSO LANDED ON RWY 29R, ABOUT 2000 TO 3000 FT BEHIND #1. HE TOO TURNED OFF ON HI SPEED TAXIWAY 'M', BUT DID NOT HEAR THE HOLDING INSTRUCTION THAT WAS ISSUED TO N61563. SINCE THE PLT (#2) OF THE TAILWHEEL EQUIPPED ACFT HAD A BLIND AREA OVER HIS NOSE, HE DID NOT REALIZE HE WAS CONVERGING ON #1. SUBSEQUENTLY, #2 (N60645) COLLIDED WITH #1 (N6L563) FROM THE REAR.THE LOCAL CONTROLLER DID NOT INFORM THE PLT OF N60645 THAT HE WAS CONVERGING ON N61563.
