<< >> NASA ASRS Report 412652, July 1998

A center controller is forced to vector an incoming B767 without prior authority/authorized while in the adjacent controller's airspace to avoid loss of separation. Traffic was an opposite direction HS25 climbing above the B767.

Narrative:

I issued a turn to air carrier X before that aircraft was in my airspace to prevent a loss of separation with another aircraft. Air carrier X was northbound level at FL390. He was transitioning from a non radar, oceanic sector to a radar sector. Cga Y was in my airspace, opposite direction on the same airway. Cga Y was restr to cross 25 mi north of flann (flann is on the boundary between the sectors) at FL410. Cga Y failed to meet the crossing restr so I turned him 40 degrees off the airway. He was at FL400 and still climbing poorly. Furthermore, it did not appear that he had executed the turn. The 2 aircraft were now approximately 30 mi apart, head-on. I radar idented air carrier X 10 mi south of flann and turned him to prevent a loss of separation.

Title: A CTR CTLR IS FORCED TO VECTOR AN INCOMING B767 WITHOUT PRIOR AUTH WHILE IN THE ADJACENT CTLR'S AIRSPACE TO AVOID LOSS OF SEPARATION. TFC WAS AN OPPOSITE DIRECTION HS25 CLBING ABOVE THE B767.

Narrative: I ISSUED A TURN TO ACR X BEFORE THAT ACFT WAS IN MY AIRSPACE TO PREVENT A LOSS OF SEPARATION WITH ANOTHER ACFT. ACR X WAS NBOUND LEVEL AT FL390. HE WAS TRANSITIONING FROM A NON RADAR, OCEANIC SECTOR TO A RADAR SECTOR. CGA Y WAS IN MY AIRSPACE, OPPOSITE DIRECTION ON THE SAME AIRWAY. CGA Y WAS RESTR TO CROSS 25 MI N OF FLANN (FLANN IS ON THE BOUNDARY BTWN THE SECTORS) AT FL410. CGA Y FAILED TO MEET THE XING RESTR SO I TURNED HIM 40 DEGS OFF THE AIRWAY. HE WAS AT FL400 AND STILL CLBING POORLY. FURTHERMORE, IT DID NOT APPEAR THAT HE HAD EXECUTED THE TURN. THE 2 ACFT WERE NOW APPROX 30 MI APART, HEAD-ON. I RADAR IDENTED ACR X 10 MI S OF FLANN AND TURNED HIM TO PREVENT A LOSS OF SEPARATION.
