United Continental Holdings Inc. says it has inspected most of the 96 planes that had been grounded while it completed an overdue maintenance check.
United spokeswoman Megan McCarthy says the checks are not expected to cause any cancellations on Wednesday. The airline canceled 15 flights because of the checks on Tuesday.
United followed a federal directive in modifying the on-board computers on the Boeing 757s in 2004. But portions of follow-up inspections were done incorrectly. Those follow-up inspections take as much as 90 minutes and were expected to be finished on Wednesday.
