Hey, I recall a story in the news earlier this year where a UA 777 from AKL to LAX diverted to either KOA or HNL due to an engine shutdown. It flew for something like 187 minutes on one engine (an ETOPS record).

Does anyone know the registration of the aircraft involved or have any articles about this event????? I'd like to know more.

Thanks, Sean.

I know my aunt was working at UA HNL Station Operations that evening and was in charge of getting the UA ground staff ready for an emergency landing in HNL and updating the fire department on the situation. The 777 ended up landing in KOA.

I can also confirm it. I believe it landed 2-3 minutes short of hitting the 180-minute ETOPS benchmark. Had it gone 187 minutes, it would have been a violation of the rule.

Not sure the reason why, but as you might expect, it was kept quiet.

Actually there was a pretty good article in Aviation Week and was reported in other places. It definitely made the aviation press. Actually, it was the longest single engine diversion ever. It occured March 17.

You may want check the NTSB database.

I'm not an ETOPS expert by any stretch of the imagination, but isn't the time requirement based solely on forecast conditions and such? If the route as planned would have been legal for ETOPS, regardless of how long the airplane flew single-engine, they'd be legal...right? I mean, obviously the time enroute estimates were off somewhat (forecast winds aloft are still not an exact science)...

I think the difference was that it went that long on 1 engine but they could have fired the other back up. The engine didn't blow or quit I believe it was over heating so they shut it down.

Record Diversion

United 777 flies for 192 min. on a single PW4077, longest ever ETOPS diversion


United Airlines' Boeing 777 carrying 255 passengers flew over the mid-Pacific Ocean against strong headwinds for 192 min. under single-engine power Mar. 17 to land without incident at Kona on the western coast of the big island of Hawaii. Boeing confirmed that it was the longest single-engine diversion during Extended Twin Operations (ETOPS) since the advent of transoceanic twin-engine flights 20 years ago by a Trans World Airlines Boeing 767-200.

United spokesman Joe Hopkins said the 777 crew shut down the No. 2 PW4077-90 power plant after the engine indication and crew alerting system (EICAS) displayed a high oil temperature and low oil quantity. The No. 1 engine powered the aircraft, operating as Flight 842, for the next 3+ hr. to the Kona landing.

THE 777 HAD DEPARTED Auckland, New Zealand, bound for Los Angeles. Hopkins said the 777 was likely well past the midway point to Hawaii when the engine was shut down. United was operating the 777 in ETOPS mode on a route that, for planning purposes, is 180 min. from a suitable airport in still air with one engine operating. A Boeing official said the crew expected a 180-min.-long diversion but the 777 encountered headwinds that extended the flight by another 12 min.

The diversion during the ETOPS portion of the flight was the third recorded for all 777s, which have completed more than 400,000 flights under the FAA rules for extended-range operations. A 767 held the previous record for diversion length, but it was "not close" to the Mar. 17 diversion time, the manufacturer's spokesman said.

A PRATT & WHITNEY OFFICIAL said a detector in the No. 2 engine showed evidence of chips. Pratt and United will investigate what caused the problem.

Hopkins said United's 777 fleet has recorded a total of 16 inflight shutdowns during all phases of flight since the carrier's first 777 flight in May 1995. The United 777s have flown 2.3 million hr. during the eight years, with an inflight engine shut down rate of 0.0021 per 1,000 engine hours. United operates 60 777s. The aircraft was expected to be out of service at Kona for at least two days, if not more. United shipped a replacement engine by air to Hawaii, but it had to be placed on an oceangoing barge to reach the Kona airport where it was to be installed. In addition to the crew on board Flight 842, 10 passengers occupied the first-class cabin, 47 were in business-class and 198 in economy. After the Kona landing, passengers were accommodated on United and other airline flights.

This also discussed when this happened in March and in that post the reg. of the aircraft is mentioned. Try the search function when it works again.

Interesting that PW refers to the PW 4090 as the PW4077-90.

Either the article is badly wrong, or we've just been mistaken.
