Factual narrative
THE ACFT DEPARTED RUNWAY 8 AT 1810 AST. THE PLT REPORTED A RT ENG FIRE AND DECLARED AN EMERGENCY. THE ACFT WAS LANDED AT 1815 AST, TURNED OFF THE RUNWAY, AND ALL THE PASSENGERS WERE EVACUATED VIA THE SLIDES. ACCORDING TO MAINTENANCE PERSONNEL IN SAN JUAN, THE #2 HIGH PRESSURE BLEED VALVE IN THE RIGHT ENGINE HAD BEEN REPLACED PRIOR TO DEPARTURE. POST INCIDENT EXAMINATION OF THE BLEED VALVE REVEALED THAT THE BAND CLAMPS THAT SECURE THE BLEED VALVE TO THE ENGINE WERE UNDERTORQUED DURING INSTALLATION, ALLOWING THE PREMATURE SEPARATION OF THE BLEED VALVE.
