Narrative:
Flight from iah-aus was routine and uneventful from our perspective, was last leg of the day. After landing runway 31R aircraft was taxied on both engines to gate, where proper company procedures were followed during shutdown. Upon return to airport the following day we learned that the #1 engine had experienced a turbine blade failure apparently during landing rollout. Nothing unusual was heard from cockpit, all engine instruments seemed normal. Since crew had no indications of malfunction until after the fact, no report of a company nature was made. After learning of the event, I felt this report might be necessary to forestall any subsequent accusations of failing to report.

Narrative: FLT FROM IAH-AUS WAS ROUTINE AND UNEVENTFUL FROM OUR PERSPECTIVE, WAS LAST LEG OF THE DAY. AFTER LNDG RWY 31R ACFT WAS TAXIED ON BOTH ENGS TO GATE, WHERE PROPER COMPANY PROCS WERE FOLLOWED DURING SHUTDOWN. UPON RETURN TO ARPT THE FOLLOWING DAY WE LEARNED THAT THE #1 ENG HAD EXPERIENCED A TURBINE BLADE FAILURE APPARENTLY DURING LNDG ROLLOUT. NOTHING UNUSUAL WAS HEARD FROM COCKPIT, ALL ENG INSTS SEEMED NORMAL. SINCE CREW HAD NO INDICATIONS OF MALFUNCTION UNTIL AFTER THE FACT, NO RPT OF A COMPANY NATURE WAS MADE. AFTER LEARNING OF THE EVENT, I FELT THIS RPT MIGHT BE NECESSARY TO FORESTALL ANY SUBSEQUENT ACCUSATIONS OF FAILING TO RPT.
