SAN FRANCISCO, California --  United Airlines plans to fully refund each passengers' ticket after the plane's engine failed over the Pacific during a flight that began in San Francisco.

The plane was headed to Honolulu after taking off from San Francisco International Airport just after 9 a.m. and landed safely at 2:42 p.m. Pacific time after the pilots called for an emergency landing.

The damaged engine is seen in video a passenger tweeted from United Flight Airlines Flight 1175.

The aircraft involved is a Boeing 777. It has two engines and is designed to fly on just one engine for more than three hours over water.

United Airlines released a statement about the incident:

"Our pilots followed all necessary protocols to safely land the aircraft. The aircraft taxied to the gate and passengers deplaned normally. United is fully cooperating with the NTSB and FAA investigation of the event. We are currently reaching out to all of our customers on this flight, and plan to fully refund every ticket."

HONOLULU (HawaiiNewsNow) -  Passengers on board a flight from San Francisco to Honolulu got quite a scare Tuesday when an engine covering apparently came off mid-flight.

United Airlines flight 1175 was met with fire trucks when it made an emergency landing at Honolulu International Airport about 1:02 p.m.

The plane was able to land safely and there were no reports of injuries. 

But passengers said there were some tense moments after the engine problem, which happened about 40 minutes before the plane was due to land.

"There was a loud bang ... and then the plane really started shaking," said passenger Allison Sudiacal. "It was like rattling and the plane was kind of shaking like boom, boom, boom."

 The good news: Sudiacal said despite the scary moments mid-air, the plane landed fairly smoothly.

"They kept us informed," said Sudiacal, who was traveling with her husband, 4-month-old son and parents-in-law.

"They let us know that we had to brace for impact in case there was a rough landing. It was scary. But they did a really good job."

Sudiacal's husband, Tim, called the flight "absolutely terrifying."

He said he couldn't see the problem engine — engine no. 2 — from where he was sitting.

"I think sometimes ignorance is bliss," he quipped.

Video posted online also showed the moments before the landing: Passengers chanted "Brace! Brace! Brace" as they neared the runway, then cheered when the plane landed without incident. 

It wasn't immediately clear what went wrong, but photos appear to show the plane with a missing engine cowling, or covering.

In a statement, United Airlines said its pilots "followed all necessary protocols to safely land the aircraft," which had 363 passengers and 10 crew members on board. 

The airline also said it is cooperating with NTSB and FAA investigations of the incident.

Audio of the pilot's discussions with air traffic control in Honolulu illustrate the tense moments just before landing.

Pilot: "If you haven't already, roll the fire trucks."

Air traffic control: "They will be standing by."

In a statement, the state Transportation Department said the United flight landed safely with Aircraft Rescue and Fire Fighting personnel standing by as a precaution. The plane has been taken to a hangar, the department said, and the incident didn't spur any delays at the airport.

  1. What happens when ground crews take too many burrito breaks and don’t speak English.

  2. I foresee a really bad day coming up for the last employee to sign off on the maintenance report on that engine.

    Someone most likely didn't double check their pre-flight list. All the cowlings should be double checked before flight as well as all the exterior removable panels and landing gear doors etc.

  3. I'll be blown away if the cause ends up being shrouded in mystery. I hope the federal investigators don't wing it. The cause should be plane as day... (okay, I'll stop here).

  4. Engine is a missing fan blade and half of the one next to it. That might account for #UA1175 missing its cowlings.

  5. The complication arises, when the engine ingests part of the inlet cowling, causing it to no longer do it's intended function of providing thrust to keep the aircraft happily flying through the air, OR part of the cowling flies off and damages a part of the wing, a flight control, or the horizontal stabilizer, causing other inflight structural failures that could negatively impact the aircraft's flight characteristics.

  6. Very similar:

  7. Yes Sir - there would have been a brown spot in the middle of my seat!
