Airwolf Aerospace has been issued an FAA STC for its permanent fix for main rotor blade delamination on the Robinson R22 and R44, an issue covered by Airworthiness Directive 2007-26-12. According to the AD, the blade skins begin to debond at the skin-to-spar bond line near the blade tip, and can separate when the bond line is exposed due to excessive erosion of the blade finish or when corrosion occurs on the internal aluminum tip cap.
