Key Takeaways:

A United Airlines Boeing 737-8 experienced a temporary rudder pedal malfunction during landing at Newark, where the pedals became "stuck" for approximately 30 seconds before resuming normal operation.
The NTSB's preliminary report suggests the malfunction was likely caused by a rollout guidance servo (SVO-730) that, though disabled, remained mechanically connected and exhibited significantly restricted movement when exposed to cold temperatures.
Post-incident, specific rudder system components were removed for examination, and after replacements, the aircraft returned to service, though the NTSB's investigation is ongoing.

The National Transportation Safety Board (NTSB) has released the preliminary report into the investigation of an apparent rudder pedal malfunction on a Boeing 737-8 in February at Newark Liberty International Airport (KEWR).

As the rudders are a flight control system, federal regulations require the NTSB be notified in the event of a malfunction. According to the report, the servo that activates the rudders may have been adversely impacted by the cold.
