Blade debonding
I got mine in the mail a few days ago. The postmark was Jan 4th, the same day the alert was issued.
I remember seeing pictures of an R44 blade that debonded at the tip, looked like a foot of skin peeled back. I read the accident report a month or more ago but, I can't remember what website it was on. I believe the location was Oz, no injuries. Seems like the paint was well eroded with bare metal exposed in the area of the debond if I recall correctly.
Even though my Raven II is new, I'll admit that I've been more closely examining the blades during preflight, even before the alert was issued.
