sawthelight - just look at the trailing edge of the average 350/355 tail rotor blade - there is an addition along the edge, which may well be bonded, but there is also a bloody great rivet at each end which has to be checked at the end of each flight. It's obviously done at the factory, but I think it could have been a tidier job, as could the hydraulic pump belt.
And speaking of starflexes, we never had one go past 1800/1900 hours - it may have been the intensive work we put them through chasing those mosquitoes along the powerlines, but they should get a lot nearer than that to their target life!
I would agree with nigelh that turbomeca are a significant problem, but we still had three months downtime on a ship waiting for a gearbox overhaul, even though the engines (Allison 250s) were ready ages before.
