I wonder just how many inflight shutdowns (just a single engine) have happend on an ETOPS flight DURING THE ETOPS PORTION OF
THE FLIGHT not 20 minutes out.
We'll about 6 months ago or so, A United 777 shut down an engine 3 hours and 12 minutes from land. While I am sure it was a nervous situation for all concerned, the plane was fine and landed without incident. Did this actually violate the ETOPS rating in that they were more than the 180 minute max from an alternate. Interesting note is that United have had only 16 inflight shutdowns of engines for the 2.3 million hours of flights on the United 777's. Only three inflight shutdowns for all 777 aircraft of any airline have been recorded during etops portions of the flights. This doesn't even mean that the engine failed, just that warning lights indicated problems, and often the warning light is the problem. I would say that this supports Concordeboys theory that the 777 and it's etops ratings border on ridiculously reliable.
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.
