Why Cargo Airlines should choose the A380 over Old 747-100/200's
NEW YORK (CNN) -- Crash investigators say they may have a new lead in the TWA Flight 800 crash: a series of problems with an electrical device in the plane's fuel system.
National Transportation Safety Board investigators are closely considering a theory that faulty wiring triggered an explosion in the center fuel tank.
The doomed aircraft experienced electrical problems in the fuel system with "some frequency" according to an investigator with the National Transportation Safety Board who did not wish his name to be used.
The investigator told CNN that repeated problems with the electronic aircraft refueling system and with the fuel flow indicator raises the possiblity that there were electrical shorts in the plane's wiring.
Minutes before the crash on July 17, the flight engineer is heard on the cockpit voice recorder saying that a fuel gauge is sticking.
Originally this was not considered significant because the flight data recorder showed all engines were fueled and operating normally.
Now, investigators think some sort of electrical short could have ignited the fumes in the fuel tank.
"If the wiring and insulation gets brittle, it begins to crack. The protective covering is worn away, so the likelihood of shorts is pretty high," said independent crash investigator Michael Hynes.
A senior investigator with the NTSB says static electricity in the fuel tank is another possible ignition source.
Sorry Whale, had to get that one in.
Go Steelers!!
