WASHINGTON, June 18 — Federal investigators say they are deeply concerned about an engine break-up that nearly destroyed a Boeing 767 on the ground in Los Angeles this month because the failure may indicate a recurrence of a problem they thought they had eliminated in 2003.
American Airlines mechanics were testing the engine on June 2 , after the crew of an earlier flight had reported it was not performing properly. During the test, an internal disk came apart, slicing open a fuel tank in the left wing; the fuel spilled onto the ground, where it caught fire. One piece of metal was thrown more than half a mile from the plane.
There were no injuries, and under the rules of the National Transportation Safety Board the event might not even qualify as an accident because there was no intention to fly the plane. But experts say that such "uncontained failures," so called because the engine cowling does not hold in the debris, resemble a roulette game.
