Even before the S92 commenced operations in Norway, numerous pilots were sceptical with regards to vibration levels and rumours of one or more cracks found on aircraft. The scepticism has been proven correct.
Passenger and pilots seats are perceived as being quite uncomfortable by many. Noise and vibration levels are not perceived as any better than the S61N, perhaps even worse.
Corrective and protective measures was taken by Helikopter Service AS from the onset. Operationally this included torque reduction based on weight, leading to somewhat lower cruise speed.
Since introduction the problems with the S92 has led to a less than favorable reputation with some passengers, to a point where influential labour organisations have raised the question of looking into the need to replace the S92 with a different aircraft based on issues relating to Health, Safety and Work Environment (HSE).
Also, local community groups along the flight track have protested in various ways, based on the high external noise levels of the aircraft. This led to noise abatement procedures being introduced, i.e. speed reduction in certain areas when overflying populated areas heading to and from offshore installations.
Hopefully the manufacturer will introduce sensible improvements in a timely manner.
Perhaps its about time Eurocopter continue the work from some years back on the so called L3, with similar cabin size to the S92?
