Boeing Co. 737 planes in storage because of the coronavirus pandemic are at risk of losing power in both engines when they fly again and must be inspected, the U.S. Federal Aviation Administration said.

The emergency order applies to about 2,000 older Next Generation and Classic versions of Boeing’s workhorse single-aisle jet in the U.S., not the grounded 737 Max. Alaska Air Group Inc. said an engine shutdown during a recent flight was probably one of four instances in which the FAA said a corroded valve caused a failure.
