Narrative:

Detroit approach control started new procedures in their new airspace change, which require aircraft to fly radials to join other radials to a VORTAC. On this occurrence, air carrier X was assigned a heading of 200 degrees to intercept the dxo VOR's 201 right (from the 3) outbnd climbing to 13000'. Handed aircraft off to the cleveland ARTCC toledo sector. Corp Y was turned the opp direction of air carrier X and assigned a heading of 130 degrees to intercept the dxo 217 degree right climbing to 13000'. The occurrence happened when both aircraft leveled at 13000', both aircraft heading for their assigned radials--but the radials at the point of intercept are less than 3 mi apart. The toledo controller was unable to climb either aircraft, when the controller was able to climb the corp Y higher. Corp Y had a very strong tail wind, and on intercept of the radial, he went through it at 13200' and less than 2 mi along side air carrier X. An expedited climb and an immediate turn of 090 degrees was issued to corp Y. Detroit approach said it was the pilot of corp Y's fault for missing the radial, regardless of the strong winds. Recommend other procedures be used at detroit approach control instead of aiming aircraft at each other.

Title: ACR X HAD LESS THAN STANDARD SEPARATION FROM CPR Y. SYSTEM ERROR. CPR Y FLEW THROUGH ASSIGNED RADIAL. PLT DEVIATION.

Narrative: DETROIT APCH CTL STARTED NEW PROCS IN THEIR NEW AIRSPACE CHANGE, WHICH REQUIRE ACFT TO FLY RADIALS TO JOIN OTHER RADIALS TO A VORTAC. ON THIS OCCURRENCE, ACR X WAS ASSIGNED A HDG OF 200 DEGS TO INTERCEPT THE DXO VOR'S 201 R (FROM THE 3) OUTBND CLBING TO 13000'. HANDED ACFT OFF TO THE CLEVELAND ARTCC TOLEDO SECTOR. CORP Y WAS TURNED THE OPP DIRECTION OF ACR X AND ASSIGNED A HDG OF 130 DEGS TO INTERCEPT THE DXO 217 DEG R CLBING TO 13000'. THE OCCURRENCE HAPPENED WHEN BOTH ACFT LEVELED AT 13000', BOTH ACFT HDG FOR THEIR ASSIGNED RADIALS--BUT THE RADIALS AT THE POINT OF INTERCEPT ARE LESS THAN 3 MI APART. THE TOLEDO CTLR WAS UNABLE TO CLB EITHER ACFT, WHEN THE CTLR WAS ABLE TO CLB THE CORP Y HIGHER. CORP Y HAD A VERY STRONG TAIL WIND, AND ON INTERCEPT OF THE RADIAL, HE WENT THROUGH IT AT 13200' AND LESS THAN 2 MI ALONG SIDE ACR X. AN EXPEDITED CLB AND AN IMMEDIATE TURN OF 090 DEGS WAS ISSUED TO CORP Y. DETROIT APCH SAID IT WAS THE PLT OF CORP Y'S FAULT FOR MISSING THE RADIAL, REGARDLESS OF THE STRONG WINDS. RECOMMEND OTHER PROCS BE USED AT DETROIT APCH CTL INSTEAD OF AIMING ACFT AT EACH OTHER.
