June 3, 1997

Incident at Gander FIR

ACA630 A320 was cleared to descend to an altitude which was 1000 feet above opposite direction traffic TSKR11 C130 (reg130306). At approximately the same time these aircraft passed, ACA630 was observed descending below the cleared altitude resulting in less than minumum separation. Update: The TCAS equipment was removed from the aircraft and sent to the manufacturer for evaluation. The TCAS manufacturer completed unit testing with the TSB and Air Canada in attendance. It was concluded through unit testing and input data analysis (Radar/Comm data and flight crew reports) that the TCAS unit operated correclty. Data analysis indicates that the crew of ACA630 initially recieved a climb Resolution Advisory. The approaching TUSKR11 traffic altitude varied plus/minus 200 feet from FL140. This oscillating altitude caused the TCAS on ACA630 to sense an Resolution Advisory Reversal (ie an initial climb Resolution reverses to descend. The Aural command "Descend, Descend Now" reported by the crew only occurs with a reversal Resolution Advisory. TSB case closed.
