Reports from the Economic Times of India noted that investigators are looking into a new angle: whether or not fuel control switches in the aircraft had been moved ahead of the aircraft’s crash. The move may have been accidental, or it may have been deliberate. But the reports noted that “…the position and movement of the engine fuel switches…” is of particular interest right now, based on a combination of factors. This combination includes flight data, voice recordings, and a set of simulations that Boeing itself conducted to aid the investigation.
A preliminary report is expected by Friday, the report noted, but one report from aviation safety expert John Cox said that an “accidental movement” would be rather difficult to pull off. The controls are apparently protected against most accidents, and are not sufficiently sensitive to move with mere jostling. But shutting off one of these switches would cause what the report called “…an almost immediate loss of power.” This again meshes well with earlier reports about the aircraft’s Ram Air Turbine (RAT) deploying.
