Narrative:

While on approach to bos 33L at about 300 AGL egpws terrain; terrain aural alert was received. The runway was in sight and VMC existed. The aircraft was configured for landing and was on glideslope and speed for landing. This was an obvious GPWS malfunction and the approach and landing was continued. Subsequently the next day on a different aircraft we received the same warning to 33L. My first officer had the same issue the prior week on a different ship. In discussing this issue with several other pilots; three said they had the same problem to both 33L and 15R. In IFR conditions this would cause a go-around at very busy airport with complex airspace.
