U.S. and European aviation authorities have ordered emergency inspections of jet engines similar to the one involved in a fatal accident earlier this week.
Airlines Almost 700 Boeing 737 engines will need to be inspected
Almost 700 Boeing 737 engines will need to be inspected worldwide over the next 20 days, regulators say.
"Fan blade failure due to cracking... could result in an engine in-flight shutdown, uncontained release of debris, [and] possible airplane decompression," the US Federal Aviation Administration (FAA) said in a statement announcing the inspections.
Fan blades that have undergone a certain number of flights will be given ultrasonic tests, they added.
Southwest Airlines Flight 1380, a Boeing 737 which was carrying 149 people, was forced to make an emergency landing at Philadelphia airport following a fault with one of its CFM56-7B engines.
An initial investigation found evidence of metal fatigue where a fan blade had broken off, according to the US National Transportation Safety Board (NTSB).
The CFM56-7B engine is in use on more than 8,000 Boeing 737 planes worldwide, the manufacturer says. ■
