The cracks were uncovered in the pylons that hold jetliners’ engines onto the wings.
Usually, pylons are inspected after a plane has gone through 1,500 takeoff and landing cycles. The cracks on one American Airline jet, however, were discovered on a plane that had fewer than 500 cycles since its last check.
It’s been reported that the size of the cracks found on American’s jets surprised the Boeing officials. One jetliner’s pylon was so badly cracked that regulators worried that the plane ran the risk of losing an engine.

In response to the discovery, Boeing is said to be stepping up inspections on 767 jetliners and considering creating new industry-wide guidelines for inspecting 767 pylons.
In addition to American, Delta and Continental also use Boeing 767 jets, and there are around 360 jetliners of the 767 model currently flying in American carrier fleets.
The aircraft is a popular model often used on trans-Atlantic flights between the U.S. and Europe. Depending on the model, the plane seats 181 to 245 passengers in three different classes.
