Boeing is cutting back on making more 737 Max airplanes, but says the move is only temporary.
The aircraft are being scrutinized after 346 people died in two crashes.
A preliminary report of last month’s crash appeared to point to a possible problem with the plane’s anti-stall system.
All of the 737 Max planes have been grounded since that crash.
The change in production rate is expected to happen in mid-April.
