The shut up gringo incident/accident cos it was a very serious one I recall was Avianca not the other AA
PB
The accident usually associated with the 'shut up gringo!' call is Avianca 11 operating CDG-MAD on November 27, 1983.
However, the published CVR transcript has no mention of the legendary last words:

Another CFIT accident sometimes claimed to have the exclaimation was Avianca 410 CUC-CTG on March 17, 1988. It was a 727 doing a high speed climb into the haze in mountainous terrain, with the FO flying and the captain chatting over his shoulder with a jumpseat rider.
I first recall hearing about this callout a couple of decades ago at the Pan Am training center in MIA. PAA trained Avianca's 747 and 727 crews in those days I believe.
