United grounds 52 777-200s due to missed inspections on-wing leading edge panels

United Airlines cancelled about 18 flights this week and removed 52 Boeing 777-200s from service as it failed to perform required inspections on the wing leading-edge panels. The issue was first reported by the Wall Street Journal. The aircraft were originally grounded last year after a Pratt and Whitney engine on a United 777-200 on a flight to Honolulu suffered failure causing debris to disperse over nearby cities. The aircraft made an emergency landing without any injures. Reuters reports that United had inspected 10 of the planes and was working with the FAA to return the others to fly in
