Bond: Findings not proved beyond reasonable doubt

Although Sheriff Principal Pyle has indicated that spalling was, on balance, the most likely reason for the catastrophic gearbox failure which caused the accident - a view not shared by the independent Air Accidents Investigation Branch - he did not find that this was not proved beyond reasonable doubt.

Additionally, he determined that even if we had followed the correct procedure it is by no means certain that the gearbox would have been removed, as there may not have been sufficient evidence of particles to warrant its removal.

But we have always accepted that we made mistakes through honest confusion over telephone calls and emails.
