NEAR COLLISION BETWEEN ACR-WDB AND SMA JUST OUTSIDE ARSA.

Narrative

DEPARTED RWY 6R AT ANC; ANCHORAGE; ON RWY HDG 065 DEGS. I; THE F/O; WAS FLYING THE ACFT. PER SID; ANC 9 DPE; COMMENCED RIGHT TURN AT ANC 9 DME; WHICH IS APPROX 3-4 MI E OF THE CENTER OF ANC ARPT. WE WERE CLBING THROUGH APPROX 1700' MSL (ABOUT 1600' AGL) AS TURN WAS STARTED. UTILIZED GRADUAL ROLL INTO TURN DUE TO HIGH OPERATING GROSS WT OF 816900 LBS AT TKOF (EQUALS 99% MAX TOGW); FLUCTUATING WINDS (PER TWR AND WINDSOCKS) AND ANC AREAS KNOWN POTENTIAL FOR SHEAR. JUST PRIOR TO INITIATING TURN; TWR GAVE US FREQ CHANGE 123.8. THIS FREQ WAS SELECTED BY CAPT AS THE TURN WAS INITIATED AND THERE WAS A CONVERSATION ON THE FREQ AT THAT MOMENT. AS WE PASSED ABOUT 15-20 DEGS OF BANK; I SPOTTED SMA Y ACFT SLIGHTLY ABOVE US AND IN ABOUT OUR 11-11:30 O'CLOCK POS AND WITHIN A FEW HUNDRED YDS. WE WERE ABOUT IN HIS 4:30-5 O'CLOCK POS AND HDG TOWARD HIM ON AN APPARENT COLLISION COURSE. I VERBALLY CALLED OUT THE TFC AND SIMULTANEOUSLY APPLIED FORWARD PRESSURE ON THE CTLS WHILE ALSO DECREASING THE BANK ANGLE SOMEWHAT TO PREVENT OUR LEFT WING FROM HITTING THE OTHER ACFT. WE THEN PASSED JUST UNDER AND SLIGHTLY TO THE RIGHT OF SMA Y. I ESTIMATE THAT WE CLRED HIM BY ABOUT 100-200' OR LESS. HE WAS WHITE AND; I THINK; BLUE IN COLOR. WE THEN CHKED WITH ANC DEP AND QUERIED THEM ABOUT THIS ACFT; ADVISING THEM OF THE NEAR COLLISION. THEY ACKNOWLEDGED AND SAID THAT HE WAS ON ANOTHER FREQ. THEN HE; THE SMA PLT; CAME ON THE FREQ WITHIN A SHORT TIME AND ACKNOWLEDGED THE NEAR MISS. WX WAS -40 SCT E 90 OVC 60; WINDS LIGHT AND VARYING FROM DIRECTIONS GREATER THAN 90 DEGS ON SURFACE; PREDOMINANTLY EASTERLY. SINCE BOTH ACFT WERE UNDER ATC CTL I FEEL THAT THE CAUSE OF THE NEAR COLLISION WAS AN ATC BREAKDOWN; LACK OF COORD BTWN TWR; DEP CTL; ETC. HAD WE BEEN IN THE CLOUDS; WE MOST LIKELY WOULD HAVE COLLIDED. ALSO; IT WOULD NOT HAVE BEEN AS CLOSE A CALL IF OUR CREW; INCLUDING MYSELF; HAD BEEN MAINTAINING A HIGHER DEGREE OF TFC WATCH. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: ON RETURN TRIP; FLT CREW HELD TELEPHONE CONFERENCE WITH 2 SUPVRS FROM ANC TWR. THEY CLAIMED THAT THIS NEAR COLLISION WAS REALLY NOBODY'S FAULT. ANALYST DISAGREES: EVEN THOUGH THE VFR SMA WAS NOT BEING 'CTLED' BY ANC APCH CTL; ANC ATC HAD A RESPONSIBILITY TO THE 2 ACFT TO EXCHANGE TFC INFO SO THAT NEITHER WOULD BE SURPRISED BY THE OTHER. THE SMA WAS VFR JUST OUTSIDE THE ARSA GOING TO AN ARPT N OF ANC. ANC TWR SHOULD HAVE BEEN ABLE TO SEE THE ACFT EITHER VISUALLY OR ON RADAR AND SHOULD HAVE GIVEN THE SMA TO THE ACR AS TFC BEFORE THE FREQ CHANGE WAS ISSUED. ANC TWR AND APCH CTL EACH HAD A GOOD OPPORTUNITY TO PREVENT THIS NEAR COLLISION AND DID NOTHING TO DO SO.
