Four Southwest planes, repaired for cracks, will likely return to service by Saturday. Airline officials say the 5th plane with cracks in the skin will be held back for additional, previously schedule maintenance.
Southwest grounded 79 of its older Boeing 737 aircraft for inspections after a hole opened in the roof of a similar plan over Arizona last week, forcing an emergency landing. The defective plane will be flown to a maintenance center for permanent repairs until Boeing determines how to fix the problem.
Boeing has already provided instructions on how to fix the cracked planes, which is usually a 2-day job.
