That is interesting. Where your blades the 'third set' in the following quoted paragraph from the article?
Two of the three blades had accumulated approximately 1,280 hours TIS and were not among the 10 blades found to have debonded between July 2006 and January 2007. Details of the third blade were not known at the time this safety recommendation letter was prepared. RHC had not reported new cases of a blade that was associated with debond between the skin and spar after January 2007.
If they are indeed yours, then strangely enough RHC couldn't recall that they had a TIS of less than 200 hours.
The article also doesn't explain why from a certain serial number the blades are deemed to be safe. No mention of a changed manufacturing process. If anybody can shed some light on this, I am lost with all the info available.
