A FULL PERFORMANCE LEVEL CONTROLLER (FPL CTLR) AT SECTOR 31 OF BOSTON ARTCC WAS GIVING FAMILIARIZATION TRAINING TO ANOTHER FPL CTLR TO FAMILIARIZE THE TRAINEE WITH A NEW AREA THAT HAD BEEN TRANSFERRED FROM NEW YORK ARTCC TO BOSTON ARTCC. SECTOR 31 WAS CONSIDERED TO BE A RATHER COMPLEX & BUSY AREA. DURING A BUSY PERIOD AFTER TRAFFIC HAD 'PEAKED', THECTLRS WERE CONCENTRATING ON A POTENTIAL CONFLICT BETWEEN 2 ACFT WHEN ONE OF THEM (EASTERN FLT 380, A BOEING 727) BEGAN CONVERGING WITH A 3RD ACFT (MAC 67947, A USAF C-141). THE CONFLICT ALERT SYSTEM ACTIVATED & THE CTLRS ISSUED A TURN TO AVOID CONVERGENCE; HOWEVER, THE 2 ACFT PASSED WITHIN 1/2 MILE OF EACH OTHER WITH THE SAME ALTITUDE ASSIGNMENT. EA380 HADBEEN ASSIGNED AN ABNORMALLY LOW ALTITUDE (FL230) FOR ITS ROUTING. THE CONFLICT OCCURRED WHEN EA380 TURNED IN RESPONSE TO AN ARTCC CLEARANCE.

Documents from the investigation the NTSB's docket: the evidence folder behind the report

The docket, the folder of records gathered during an investigation (maintenance records, photographs, witness statements, examinations), has not been read from the NTSB for this case yet; the list appears here once it has. Open the docket at the NTSB.

Everything on this page comes from the NTSB's public records. The narrative, probable cause and findings are the NTSB's own words; the coded tables behind the report are written out in plain English, with pilots' ages, home towns and medical details left out. The documents and photographs are the NTSB's docket, shown as the NTSB released them. This site's own text never names anyone involved. A preliminary report can change; the final report usually follows one to two years later, and the page is refreshed when it does.
