The Federal Aviation Administration is ordering emergency inspections of about 2,000 Boeing 737 airplanes due to a attainable engine valve downside that would result in engine failure.

The FAA’s emergency air worthiness directive orders inspections of older 737 Classic and Next Generation planes that will have been in storage because of sharply decreased air journey demand through the COVID-19 pandemic.

The directive, dated Thursday, was prompted by 4 latest reviews of single-engine failures because of issues with a essential air examine valve. Inspectors discovered corrosion on some engine air examine valves, which may lead the valves to develop into caught open and doubtlessly trigger each of a airplane’s engines to lose energy and forestall them from restarting.

“If this valve opens normally at takeoff power, it may become stuck in the open position during flight and fail to close when power is reduced at top of descent, resulting in an unrecoverable compressor stall and the inability to restart the engine,” the directive states. “Corrosion of these valves on both engines could result in a dual-engine power loss without the ability to restart. This condition, if not addressed, could result in compressor stalls and dual-engine power loss without the ability to restart, which could result in a forced off-airport landing.”

The directive requires airways and different plane homeowners and operators to examine the valves on all of their 737 Classics and 737 NGs that haven’t been in operation for seven or extra consecutive days.

In a press release, Boeing says that “with airplanes being stored or used infrequently due to lower demand during the COVID-19 pandemic, the valve can be more susceptible to corrosion.”

Boeing says it’s offering inspection and alternative info to fleet homeowners in the event that they uncover a problem.

The valve downside isn’t associated to Boeing’s grounded 737 Max plane.
