U.S. aviation regulators are expected to “impose emergency inspection requirements for certain jet engines,” like the Boeing 737, that go beyond policies proposed in the wake of the Southwest Airlines engine explosion, according to The Wall Street Journal. These changes could come as soon as Friday, sources told the Journal. The Federal Aviation Administration will reportedly “require some older engines to undergo ultrasound inspection within 20 days,” in tandem with European and plane-specific regulations. The Southwest incident killed one and injured several others.
