The FAA said the inspection mandate applies to CFM56-7B engines that have made 30,000 trips since their last inspection. Those engines must undergo inspections within 20 days. The FAA said General Electric, the engine’s manufacturer, estimates that the corrective action affects 352 engines in the United States and 681 engines worldwide.
Southwest Airlines took the unusual step of announcing it already was complying with the directive, issuing a statement that said:
“Southwest Airlines Co. acknowledges the issuance of Emergency Airworthiness Directive (AD) 2018-09-51 by the Federal Aviation Administration to airlines operating CFM56-7B engines. The existing Southwest Airlines maintenance program meets or exceeds all the requirements specified in the Airworthiness Directive.”
Jennifer Riordan, a 43-year-old bank executive and mother of two from Albuquerque, was killed Tuesday when the engine exploded.
