The Longest ETOPS S.E. Diversion (thus far)
The longest ETOPS-related emergency flight diversion (192 min. under one engine power) was conducted on a United Airlines' Boeing 777-200ER, carrying 255 passengers, on March 17, 2003 over the southern Pacific ocean.
UA842 from AKL to LAX on 17.March 2003 was forced to fly a 190min
diversion on 1 engine over the Pacific. The captain had to shut
down the number 2 engine (PW4090) because the oil pressure
dropped dramatically. The aircraft (N780UA) was diverted to KOA (Kona Intl)and
it landed safely. Indications are that the engine may have
suffered a bearing failure. UA says that the time on 1 engine
was just over 3 hours, but the FAA says it was 190 to 193min.
