Human Factors
On approach to 31L ILS and just inside final approach fix in VMC; we received an RA to climb. We disconnected the autopilot and complied with the RA. We climbed very briefly before the RA stopped. The target aircraft passed 200-300 FT below us. We advised Tower of the RA and descended back to the glide-slope. Tower called the traffic just prior to the RA. Normal approach after recovery. RA received just after hand off from Approach Control to Tower frequency.
B737 Captain reports a TCAS RA inside DUANE during the ILS 31L approach to BFI. Evasive action is taken and the intruder passes 300 FT below the B737.
