here are a few photos of the latest blades.
there seems to be an indentation near the doubler on the first pic as well as the crack, hasn't been ascertained what the cause is.
the severe ripples on the 63" station of both blades is also a mystery as there is no impact damage evident at all anywhere on the blades.
the delamination is hard to see in the photograph.on the orange upper section but is easy to see in real life.
these blades are outside the batch numbers of the original problem blades so the base is widening.
they are just over 300 hours in service so please this problem has nothing to do with high temperatures or over running times or flies. or misuse.
the fact is that contrary to some writers opinions mustering machines flown by experienced pilots (most are) do not pull heaps of power all day long playing silly buggers in the trees. most pilots use minimal power at slower speeds and get the optimum performance at low power settings. (i fly with these pilots regularly). no-one is in a hurry.
