American Airlines grounds flights / American Airlines cancela vuelos

American Airlines cancelled about 850 flights on Wednesday after it grounded its MD-80 aircraft to conduct extra safety inspections on wiring.
The cancellations - more than a third of its schedule - came after almost 500 flights were scrapped on Tuesday.
The Federal Aviation Administration (FAA) raised concerns about the wiring inspections two weeks ago.
The FAA has been clamping down on safety inspections and several airlines have been forced to ground planes.
Southwest, Delta and United have also grounded some of their fleets to carry out inspections.
Missed inspections
The FAA said that it had checked several American MD-80s and decided that the work carried out two weeks ago did not meet its standards.
The airline runs about 2,300 flights a day, more than one third of which use MD-80s, mainly on mid-range flights.
The FAA has been tightening up its inspections since admitting that it was too lax with Southwest Airlines last year.
The House of Representatives' Transportation Committee discovered that fuselage cracks on Southwest planes had gone undetected due to missed inspections.
The Senate is holding its latest set of hearings on airline maintenance and inspection on Thursday.
