Narrative:

I have been informed of an intent to file a deviation report on me for exceeding 250 knots below 10;000 feet on the subject flight. I was one of two relief pilots on this flight and I cannot specifically recall if I was in the first observer's seat or second observer's seat. I also do not recall which pilot was the pilot flying or which the pilot monitoring on this flight. I had no recollection of this event until I reviewed the maintenance history of the aircraft which jogged my memory somewhat. I recall that there was an issue with the FMC and that its response based on programmed entries was not expected by the crew. I believe one or more crew members immediately commented so that immediate correction was made; but not before the exceedance. The captain wrote up the discrepancy upon arrival at the gate. Obviously; I/we should have immediately associated this with an event requiring an as soon as possible report.I believe [the cause of this event] was an unexpected response of the aircraft automation to pilot input into FMC. Obviously; the crew must be responsive to quickly correct even unexpected aircraft deviations. I think the pilot flying was immediately responsive to this event; as I recall; correcting the deviation to the best of human capabilities.obviously we all should have discussed submission of a safety report. If others submitted one they were smarter than me. I would never intentionally violate operating rules; and I take this very seriously. In the future I will recall this event and even if any doubt exists; submit a safety report.

Title: Three weeks after the 'event' the FAA sought retribution from a B-777 flight crew for exceeding 250K below 10;000 on arrival at their destination. The source of their information was a routine review of the AML in which the flight crew had written up anomalous behavior of the autoflight system while operating with the autopilot engaged in LNAV and VNAV modes. The anomalous behavior described consisted of turning the wrong way at a waypoint and exceeding 250 knots below 10;000 feet. Both anomalous actions were immediately resolved by the crew and; again; written up in the AML.
