Includes the comments that "On approach into LGA, the first officer was the pilot flying and the captain was the pilot monitoring. SWA 345 was cleared for the ILS Runway 4 approach. ... SWA 345 proceeded on the approach when at a point below 400 feet, there was an exchange of control of the airplane and the captain became the flying pilot and made the landing."
