Lets go back a bit, blades start peeling Robinson say it is because you have not kept the paint on leading edge joint ? so AW get STC for tape to overcome problem of paint erosion?, I would expect that part of the AW instructions was to at least touch up paint before fitting tapes.(don't know never seen kit)
Wonder if this affected someone's bottom line.
Seen tapes last 12 months on a 300 used for training, the blades & tape want to be at least warm when fitting, and left for few hour before flying.
strey
Are you flying in rain\snow or heavy dust conditions
Interesting wording, from the AD (my bold)
We do not believe that this blade debond is due to a manufacturing problem. This debond issue appears to be due to the basic design and maintenance, and the actions taken in AD 2007-26-12 have been shown to detect and to prevent the debond problem. However, reliance on continued inspections
is an inadequate long term solution. We are considering a subsequent AD to terminate the inspection requirement by mandating the replacement of these rotor blades.
