DENVER (KDVR) — A United flight diverted to Denver after crews reported an issue with an engine.

United Airlines confirmed to FOX31 that a flight from San Francisco to Paris had to land at Denver International Airport Thursday evening.

Crew members on the Boeing 777-200 reported having an issue with one engine. Even though the issues were reported, United said the flight did not declare an emergency landing, but emergency services were standing by for the plane’s arrival as a precaution.

United said the flight landed safely, and all 273 passengers and 12 crew members deplaned.

Since the flight was canceled upon arrival in Denver, passengers are still waiting for their next available flight to Paris. United said it is working with customers to find flight options on Friday.

This isn’t the first United flight that had to be diverted to Denver mid-trip this year.

A month ago on Feb. 19, another United flight left from San Francisco and had to divert to Denver due to a wing issue. The flight was headed to Boston.

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

On Jan. 27, a United flight that left from Las Vegas landed shortly after in Denver due to a cracked windshield. This flight was originally headed to Washington D.C.

Boeing has faced several issues and investigations in the past few months over the quality and safety of their aircraft. On March 25, it was announced that Boeing CEO Dave Calhoun would step down from the embattled plane maker at the end of the year.
