Hi,
Hopefully this wont be regarded as too much thread creep... IMHO as a Sumburgh radar controller bod, the BHL S92's appear to have been alot more reliable than the CHC aberdeen equivalent. I've seen maybe the odd day with only 4 or 5 airframes flying out the 6 but this seems very rare. I understand there was initial tail rotor gearbox issues wither water ingress, but this appears to have been remidied.
