Southwest Airlines found no fuselage issues during inspections of its Boeing 737-300 fleet following the emergency landing of one such aircraft after its cabin depressurized on 13 July.
Overnight and early morning inspections delayed roughly 20 morning flights today for an average of 30 minutes, a Southwest spokeswoman says, adding that inspections "did not find any issues on any of the aircraft".
The low-cost carrier's findings come as investigators from the US National Transportation Safety Board (NTSB) examine the emergency landing, which occurred at Yeager airport in Charleston, West Virginia.
The aircraft was en route from Nashville to Baltimore Washington International airport when it experienced rapid decompression around 30min into the 16:05EST service.
Upon examination after the emergency landing, a 1ft hole was discovered in the top of the fuselage.
During a conference call today to discuss the Senate version of FAA Reauthorization, the head of the chamber's Commerce and Transportation Committee John Rockefeller said FAA was updating legislators on the incident later today. He characterised the incident as a "very odd situation".
