Southwest released new information concerning the ongoing investigation of their aircraft after one of their planes had to make an emergency landing on Friday.
Southwest canceled 70 flights Monday and hundreds over the weekend so they could investigate the fleet. The company said the airline has inspected about 90 percent of the 79 Boeing 737-300 aircraft. Out of the 67 aircraft inspected, three planes had subsurface cracks and will remain out-of-service until the appropriate repairs are made.
The National Transportation Safety Board is still looking into what caused the 5-foot hole in the passenger cabin of the aircraft on Friday. Just 18 minutes into the flight, a top panel flew off the plane forcing flight passengers to wear oxygen masks until the plane landed safely. There are no reports of serious injuries.
Boeing, the aircraft manufacturer, is conducting an additional investigation to make sure there are no other damages in the remaining aircraft in the sub-fleet. Southwest said it anticipates to complete the inspections by Tuesday evening. The airline encourages customers to check the company website for flight changes as a result of inspections and out-of-service aircraft.
