G'Day Robborider and Mr Selfish
AD/R22/31 amendment 6 has just been released (Fri 8/8 in the pm)
The long and the short of it is that it states that any R22 that has conducted more than 50 hours mustering must have it's MR blades retired before 1500 hours time in service. It states that the eddy current inspection has been removed on the advice of the manufacturer.
It also goes on to say that any blades that are retired at 1500 hours should be retained "as future developments may enable them to be placed back into service"
