General Maintenance Action
Aircraft; Weather
We were flying a visual RNAV 31L approach to PSP. The weather was VFR. The winds on the runway were 350 at 7 kts. There was moderate turbulence during the entire approach. The First Officer (FO) and I had thoroughly briefed the approach and weather conditions. On the way down final; we had a quartering tailwind at between 15-17 kts. The airplane was fully configured and on speed by 1;500 feet. We had a visual on the runway; and were using the RNAV approach as backup. Approximately at 400 feet; we received a sink rate GPWS alert. I shallowed the descent. On short final there was another momentary sink rate call from GPWS. The FO stated later that the descent rate was never more than 1;000 fpm. As we were in the flare; in the touchdown zone; we got a GPWS too low terrain call. There was obviously conflicting information. Since we were on the right runway; fully configured and stable; I landed the airplane. The landing was uneventful. When we arrived at the gate; we called Maintenance and wrote up the GPWS system. Looking at the maintenance history; there had been 2 previous GPWS write ups within 4 days.
