This is breaking news, but a Asiana 777 just went down at SFO.
the 777 is one of Boeing's best designs, designed initially for long haul, large service
with twin engines for trans-oceanic flight, the 777 has logged billions of miles with
few incidents. According to wikipedia only 1 person has died in a ground fueling fire
and only 2 hulls have been totally lost.
Passenger count is unknown but casualties must be expected.
I will update as we learn more.
God Help Those on Board.
God Speed the EMS personnel of San Francisco.
The type's first hull-loss occurred on January 17, 2008, when British Airways Flight 38, a 777-200ER with Rolls-Royce Trent 895 engines flying from Beijing to London, crash-landed approximately 1,000 feet (300 m) short of Heathrow Airport's runway 27L and slid onto the runway's threshold. There were 47 injuries and no fatalities. The impact damaged the landing gear, wing roots, and engines, and the aircraft was written off.[195][196] Upon investigation, the accident was blamed on ice crystals from the fuel system clogging the fuel-oil heat exchanger (FOHE).[189] Air accident investigators called for this component on the Trent 800 series engine to be redesigned in 2009.[197] Redesigned fuel oil heat exchangers were installed in British Airways' 777s by October 2009.[198]
Two other minor momentary losses of thrust with Trent 895 engines occurred in February and November 2008.[199][200] The National Transportation Safety Board (NTSB) investigators concluded that, just as on BA38, the loss of power was caused by ice in the fuel clogging the fuel-oil heat exchanger. As a result, the heat exchanger was redesigned.[189]
The type's second hull-loss occurred on July 29, 2011, when an EgyptAir 777-200ER registered as SU-GBP suffered a cockpit fire while parked at the gate at Cairo International Airport.[201] The plane was successfully evacuated with no injuries,[201] and airport fire teams extinguished the fire.[202] The aircraft sustained structural, heat, and smoke damage, and was written off.[201][202] Investigators focused on a possible electrical fault with a supply hose in the cockpit crew oxygen system.[201]
Given the decades of service, this is one of the best performing aircraft in the history
books.
We have no details on Asiana, but must wait for an initial statement.
I hope this is not a fuel system problem.
