Boeing said it has reminded operators of the actions that flight crews should take if they encounter rudder restriction. 
The Federal Aviation Administration issued a safety alert to airlines regarding Boeing 737 airplanes equipped with certain rudder components.

The air-safety regulator said Tuesday the operators of Boeing 737 NG and 737 MAX airplanes with SVO-730 rudder rollout guidance actuators should instruct flight crews that the rudder control system could potentially become jammed or restricted in flight or during landing.

Boeing said in a statement it has reminded operators of the proper actions that flight crews should take if they encounter rudder restriction, and has also shared technical guidance from its supplier.

“We continue to work under the oversight of regulators regarding the actuator on an optional autoland system on a subset of 737s,” Boeing said.
