## Analysis (aircraft 2)

ACFT NEARLY COLLIDED WITH PAA N82NA AT FL370 ABOUT 200 MI EAST OF MIAMI WHEN ACFT PASSED ABOUT 300 FT FROM EACH OTHER INA NONRADAR ENVIRONMENT. BOTH ACFT WERE AT THEIR ASSIGNED FLIGHT LEVEL & WERE OPERATING ON ROUTES APPROVED & ISSUED BY MIAMI ARTCC. THE D72 CONTROLLER(CTLR) FAILED TO COORDINATE THE ALT OF N656PA WITH THE D81 CTLR, FAILED TO NOTE CONFLICT WHEN HE APPROVED FL370 FOR N82NA, & PLACED FLT PROGRESS STRIP FOR N82NA IN WRONG BAY AT SECTOR 72 POSITION. ADDITIONALLY, D81 & R81 CTLRS FAILED TO DETECT CONFLICT BETWEEN THE TWO ACFT. THE R72 CTLR DID NOT CAREFULLY READ THE STRIP WHEN HE FOUND IT. THE BOARD ALSO FOUND THE QUALITY ASSURANCE EFFORTS AT THE MIAMI ARTCC TO BE DEFICIENT.
