From the lawsuit:
He was referring to an interim report by the Air Accident Investigation Unit (AAIU) which was published last February and identified a problem with the sensor on the right-side engine of the plane.
The report found that there was a flaw with the fuel transmission to this right-hand side engine which could have been giving more power than the left-hand side engine. This means there was a potential for the plane to be unbalanced as it landed.
The crew made three attempts at landing. I am no expert but I would have thought that they would have detected this imbalance on the first attempt and compensated accordingly. This suit IMHO is a blatant attempt at screwing money out of companies who can appear to afford it. Like you, AK, I hope it comes to nought.
