Vuelopedia is a work in progress: it currently holds about 30% of the information we expect to have by the third quarter of 2027. Although we use only official, highly reliable sources, some aircraft data and history may still contain errors or inaccuracies. We work hard to clear every anomaly from the records using specialized verification tools.

Accident at Valdosta, Georgia

On February 22, 2008, the Boeing 737-700 aircraft (registration N551WN), operated by Southwest Airlines, was involved in an accident at Valdosta, Georgia (United States), leaving 1 injured. Source: the NTSB (United States).

What happened

On 22 February 2008, a Boeing 737-700 was at 30,000 feet, on the arrival for landing, when it met unexpected turbulence. The pilot flying described it as at least moderate in intensity and lasting about 10 seconds; the autopilot stayed engaged. The seatbelt sign was on and the flight attendants were securing the passenger cabin for landing. One flight attendant was thrown against a bulkhead and suffered a fractured ankle. The aircraft then landed without further incident. Source: the NTSB (United States).

Incident at Chicago, Illinois

On October 1, 2008, the Boeing 737 aircraft (registration N551WN), operated by Southwest Airlines, was involved in an incident at Chicago, Illinois (United States). Source: the NTSB (United States).

What happened

On 1 October 2008, on leaving the runway after landing, the aircraft lost the right nose gear wheel assembly. Metallurgical examination revealed that the nose gear axle fractured in a transverse plane: it showed intergranular fissures that acted as stress concentrators and from which fatigue cracks propagated. The failure of the right-side inner trunnion, on the gear's inner cylinder, was most probably due to the prior failure of a tapered roller bearing. Over time, the size of the fatigue crack and the landing loads were enough to take the fissure into overstress and break the trunnion. The change of aircraft ownership and the monthly exchange of bearings and wheels made it difficult to determine when the bearing failed and why. Source: the NTSB (United States).
