US FAA issues safety alert over Boeing 737 rudder issue
WASHINGTON (Reuters) - The Federal Aviation Administration said on Tuesday it issued, opens new tab a safety alert to airlines warning of the potential for limited or jammed rudder movement on certain Boeing 737 airplanes after a safety official urged the agency to take action.
The National Transportation Safety Board on Sept. 26 issued urgent safety recommendations to Boeing and the FAA after investigating the potential for rudder issues in some 737 airplanes, which prompted the FAA to convene a corrective action review board.
The NTSB recommendation came as they investigate a February incident involving a United Airlines (UAL.O), opens new tab flight.
The safety alert directs pilots and airline operators to review Boeing's procedure for responding to a jammed rudder but does not require airlines to replace the parts that can stick.
Last week, the NTSB said more than 40 foreign operators of Boeing (BA.N), opens new tab 737 airplanes may be using 737 or 737 Next Generation planes with rudder components that could pose safety risks.
The FAA said the alert provides information on an existing automated check of the rudder system "that would identify limited or jammed rudder movement during approach prior to landing" and said airlines should warn pilots the rudder "could potentially become jammed or restricted in flight or during landing due to moisture that could accumulate and freeze."
Boeing earlier informed affected 737 operators of a "potential condition with the rudder rollout guidance actuator" in August, in what is known as a Multi Operator Message.
Boeing said Tuesday it continues to work under the oversight of regulators and has "reminded operators of the proper actions that flight crews should take if they encounter rudder restriction."
