Fuel contamination
Can anyone explain to me why fuel contamination cant be an issue here? There appears to be agreement that after a sortie of this length, the aircraft would be operating from the lower reaches of the tanks. If there was sufficient liquid in the tanks, there would be normal readings and no warnings activated. If the liquid wasnt fuel.....
With the onset of contaminated fuel being ingested, would the pilot not be quite confused by the symptoms (no criticism implied) and from what has been written, have about a minute before the other engine was similarly afflicted?
Could explain the popping etc sounds reported by witnesses, the stopped engines at impact, and the lack of fire. Could it not also have contributed to a loss of height before the decision to auto rotate was taken? Given that height for a successful autorotation was likely at a premium even in the cruise.....
The blades may have been turning very slowly at impact as a result of a desperate attempt to arrest the rate of descent, realising a successful landing was not possible. The final irony being that the pub roof by virtue of its unusual construction provided a degree of cushioning of the impact, but sadly not enough
