(CNN) — According to a Federal Aviation Administration (FAA) summary in English, a Houston-bound Boeing 737-800 operated by Southwest Airlines returned safely to Denver International Airport this Sunday.
The agency said an investigation would be conducted into the incident.
The failure is the latest in a series of mechanical failures that have plagued Boeing planes from various airlines in recent months. The company has faced criticism over the years over the safety of its planes.
Boeing declined to comment and referred CNN to Southwest for information on the aircraft and fleet operations.
In a statement to CNN, Southwest said passengers would take another flight to Houston and arrive about three hours late.
“We apologize for the inconvenience of your delay, but we prioritize the safety of our customers and employees,” the statement said. Southwest confirmed there were no injuries.
Southwest had its maintenance crew check the plane for 35 minutes before it was forced to turn around and land. According to FAA records, the plane was deemed airworthy in May 2015.
