A United flight was forced to divert to Denver after crews alerted to an issue with the plane's engine on Thursday evening.

United Airlines confirmed that a flight from San Francisco to Paris had to land at Denver International Airport.

Emergency services were on standby for the arrival of a Boeing 777-200 aircraft due to a reported engine issue. Although United Airlines said the flight did not declare an emergency landing, precautionary measures were taken for any potential situations.

The flight landed safely with all 273 passengers and 12 crew members deplaned.

Following the cancellation of the flight upon reaching Denver, passengers are currently waiting for the next available flight to Paris.

United said it is working with customers to find flight options on Friday.

This is far from new for both United Airlines and Boeing aircraft. On Feb. 19, another United flight that left from San Francisco and was heading to Boston had to divert to Denver due to a wing issue.

The Boeing 757-200 had to land due to minor damage on the right wing.

Then again, on Jan. 27, a United flight departing from Las Vegas headed for Washington, D.C., also landed shortly after take-off in Denver due to a cracked windshield.

Over the past few months, Boeing has encountered numerous challenges and undergone investigations regarding the quality and safety of its aircraft.

On March 25, it was revealed that Boeing CEO Dave Calhoun would step down from his position at the troubled aviation company by the end of the year.
