1997-02-04: TWA 842, a Boeing 767, was out of Kennedy Airport enroute to Milano. At 0253Z the crew advised they had a compressor problem with the right engine. An emergency was declared and the contingency procedure was followed down to FL260
. The aircraft was then cleared direct to Gander. The crew advised that the right engine was at idle and the landing would be carried out as such. CFR was standing by when the B767 made an uneventful landing. TSB noted that prior to the compressor stall(s) the aircraft had entered an area of turbulence and had experienced a loss of airspeed. As a result, the auto throttle set climb power, it was about this time the compressor stall problem started. Maintenance found no evidence of engine damage and adjusted the Engine Variable Bleed Control. A ground run was carried out and the aircraft was returned to service. TSB closed.
