Narrative:

The BA4100 in which I was first officer (PNF, part 121 carrier) made a slightly fast, but otherwise normal and uneventful touchdown at bos in VMC with a slight tailwind. Upon exiting the runway for taxi to gate, tower informed us that right engine was smoking badly. We simultaneously received visual and aural warning of low oil pressure on this engine, and also confirmed smoke visually through aircraft windows. We then executed engine shutdown procedures and checklist. At which point smoke ceased. At no time did we receive any fire or other abnormal indications or warnings, although the low oil pressure prior to shutdown suggests that engine may have shut itself down during taxi. Crash fire rescue equipment crew did not see any flame, further smoke, or damage. No evacuate/evacuation was deemed necessary, and we taxied and deplaned normally. Subsequent engine runup showed erratic and abnormally high torque indications in ground range. No other information available to me on causes, or further diagnosis.

Title: A BA4100 JETSTREAM FLC IS ALERTED TO SMOKE EMANATING FROM THEIR R ENG WHICH REQUIRED AN INFLT ENG SHUTDOWN ASSOCIATED WITH A LOSS OF OIL PRESSURE AT BOS, MA.

Narrative: THE BA4100 IN WHICH I WAS FO (PNF, PART 121 CARRIER) MADE A SLIGHTLY FAST, BUT OTHERWISE NORMAL AND UNEVENTFUL TOUCHDOWN AT BOS IN VMC WITH A SLIGHT TAILWIND. UPON EXITING THE RWY FOR TAXI TO GATE, TWR INFORMED US THAT R ENG WAS SMOKING BADLY. WE SIMULTANEOUSLY RECEIVED VISUAL AND AURAL WARNING OF LOW OIL PRESSURE ON THIS ENG, AND ALSO CONFIRMED SMOKE VISUALLY THROUGH ACFT WINDOWS. WE THEN EXECUTED ENG SHUTDOWN PROCS AND CHKLIST. AT WHICH POINT SMOKE CEASED. AT NO TIME DID WE RECEIVE ANY FIRE OR OTHER ABNORMAL INDICATIONS OR WARNINGS, ALTHOUGH THE LOW OIL PRESSURE PRIOR TO SHUTDOWN SUGGESTS THAT ENG MAY HAVE SHUT ITSELF DOWN DURING TAXI. CFR CREW DID NOT SEE ANY FLAME, FURTHER SMOKE, OR DAMAGE. NO EVAC WAS DEEMED NECESSARY, AND WE TAXIED AND DEPLANED NORMALLY. SUBSEQUENT ENG RUNUP SHOWED ERRATIC AND ABNORMALLY HIGH TORQUE INDICATIONS IN GND RANGE. NO OTHER INFO AVAILABLE TO ME ON CAUSES, OR FURTHER DIAGNOSIS.
