United Continental Airlines, Delta Air Lines, American Airlines and other U.S. carriers may need to inspect their Boeing 767s twice as often after one operator found “significant crack sizes” sooner than expected.
Airlines should inspect 417 of the twin-engine jets after 2,000 flight cycles or 6,000 flight hours, double the current requirement, the Federal Aviation Administration said in a proposal to be published in the Federal Register next week.
The FAA is proposing heightened scrutiny of the wing skin after cracks as large as a half-inch (1.3 centimeters) were found on either side of a fastener hole on a plane that had 18,900 flight cycles and 89,500 total flight hours.
