US and European airline regulators on Friday ordered emergency inspections within 20 days of nearly 700 aircraft engines similar to the one involved in a fatal Southwest Airlines engine blowout earlier this week, citing risks of a similar mishap.
The directives by the US Federal Aviation Administration and the European Aviation Safety Agency for inspections of CFM56-7B engines, made by CFM International, indicated rising concerns since a similar failure in 2016 of the same type of engine.
The engine explosion on Southwest Airlines flight 1380 on Tuesday was caused by a fan blade that broke off, the FAA said. The blast shattered a window, killing a passenger, in the first US passenger airline fatality since 2009.
The unsafe condition,” the FAA said in the order, “is likely to exist or develop in other products of the same design.”
The inspections ordered are a sharp step-up from actions by both the European and US regulators after a Southwest flight in August 2016 made a safe emergency landing in Pensacola, Florida, after a fan blade separated from the same type of engine and debris ripped a hole above the left wing. The European agency had given airlines nine months to check engines, while US regulators still were considering what to do.
