Aircraft
After [we had] a very smooth touch down as the weight settled on the wheels the aircraft violently pitched up. WAG about 5. I have been on the 756 for almost 20 years; and I have flown the -300 since it came on the property. The 200 has never done this. However this is the second time in about 6 months that I have had this happen on the -300. First time I wrote it up in the maintenance log; but Maintenance found nothing wrong with the aircraft. Fortunately having seen it I knew what it was doing as it happened and was not as surprised as the first time. I am not the ace of the base; but I know when an airplane is doing something it shouldn't be doing. In both cases the First Officer agreed that it was not a control input on my part. Discussing this with other pilots I have had some tell me they too had it happen and it scared the heck out of them. This airplane is doing something funny; and it needs to be looked in to. Feel free to call me to discuss particulars.
A B757-300 Captain reported that the aircraft pitched up violently for unknown reasons after a smooth landing as the aircraft settle on the wheels. This was the reporter's second such event in six months.
