What happened
The captain was conducting an ILS approach to runway 19R when a fog bank rolled over the runway during the landing flare. This caused the pilot to lose sight of the runway, prompting the initiation of a go-around.
During the go-around procedure, the aircraft veered to the right and traveled on a course parallel to the runway. The flight subsequently returned for a second approach, which was completed without further incident. After landing on runway 19R and parking at the gate, ground personnel notified the crew that the No. 4 engine nacelle and the right wing tip had sustained damage.
The investigation
Data from the digital flight data recorder indicated that during the five-second period following the start of the go-around, the aircraft's roll attitude shifted from wings level to 24 degrees with the right wing down. During this same interval, the radio altimeter increased from 1.8 feet to 29.2 feet.
Radar data confirmed the aircraft's deviation to a course parallel to the runway. Investigators located debris from the No. 4 engine nacelle on the right side of the runway, approximately 1400 meters from the threshold. Notably, no scrape marks were identified on the runway surface.
