A Southwest Airlines Boeing 737-800, registration N441WN performing flight WN-1152 from Nashville,TN to Knoxville,TN (USA), was cleared for takeoff from Nashville's runway 02R and was in the initial climb out, when the crew of WN-507 decided to go around. Tower instructed WN-507 to climb to 2000 feet and subsequently to turn right onto a heading of 110, then instructed the aircraft to climb to 3000 feet, querying WN-1152 to stop climb at 2000 feet, the crew reported they were already above 2000 feet, hence tower instructed WN-507 to maintain 2000 feet. WN-507 descended to about 1500 feet MSL, the crew reported they reacted to a TCAS resolution advisory. Following the ATC instruction to maintain 2000 feet WN-1152 began to level off at about 2200 feet but then climbed again.
WN-507 positioned for another approach to runway 02L and landed safely about 12 minutes later. WN-1152 continued to destination and landed without further incident.
According to ADS-B data transmitted by both aircraft the separation between the aircraft reduced to about 400 feet vertical and less than 0.08nm horizontal at 22:37:31Z.
The airline reported WN-507 initiated the go around due to the gusty wings.
The FAA is investigating the occurrence.
