FAA Issues Emergency Inspection Order for 737s Due to Engine Shutdown Issue

The order applies to 737s that have not flown in at least a week

The top U.S. aviation regulator issued an emergency order requiring operators of the Boeing 737 passenger jet to inspect and potentially replace a key engine component, following four reports of unexpected engine shutdowns.

The FAA's "emergency airworthiness directive" applies to any 737 that has been in storage, which covers any plane that has not been flown in a week. Operators will be required to inspect and potentially replace a certain valve that can get stuck in the open position.

The FAA said it had four recent reports of engines shutting down because of that stuck valve condition.

"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 indicated.

With thousands of 737s in fleets worldwide, the order could have far-reaching effects on airlines, particularly given how many planes are sitting idle thanks to the coronavirus pandemic.

The order also comes as Boeing works to get the 737 Max back into the air; that fleet has been grounded for 16 months following two fatal crashes. CNBC reported Thursday that a key supplier is telling backers to expect sharply lower deliveries of that plane than once forecast.
