Human Factors
The EMB190 was climbing out of BOS cleared via the SSOXS 3 departure. While on a land line doing a point out; I noticed the flight take a hard right turn into Sector 47. At the same time; Boston Approach called to inform me of the same thing. I immediately turned the pilot southeast on a 160 heading (which I noticed later he didn't even do). I queried the pilot as to their cleared route of flight and the fix to which they were navigating. They said they were cleared via the SSOXS 3 departure and were navigating to 'Weymouth' or 'Plymouth'. I honestly couldn't make it out. Weymouth doesn't make sense because that airport closed about a decade ago. But I can't imagine how any one of the Plymouth navaids (airport; NDB) could have possibly found their way into that departure.This is literally the third EMB190 SSOXS 3 departure issue I've had within less than two years; all from the same company. Each time; they take these crazy right-hand turns on about a 270 heading. Is there some systemic issue we're missing with regard to this particular airline; aircraft; or FMS system/software? It may be time to investigate.
The reporter states that the EMB190 was passed to him heading roughly south and proceeding direct to SSOXS when the sudden turn to the west occurred. When queried the pilot seemed to know that an error had been made and replied that he was turning back to SSOXS. This event occurred 6 to 8 NM north of SSOXS and their route of flight after SSOXS was over BUZRD and SEY. Unfortunately; no request for a phone call was made by the reporter and no clear explanation for the turn is available.
ZBW Controller reports an EMB190 making a sudden right turn at 14;000 FT on departure from BOS. The reporter has seen this turn happen twice before; each time by the same aircraft type and same company; and wonders if there is some FMS or software issue.
